in https://forum.nim-lang.org/t/12463 which seems reasonable enough to
me.
stdlib has several dozens of places doing result.setLen now, but if
`experimental:strictDefs` move sot on by default and there is no easy
way to locally suppress the warning we can revisit this.

fixes #24054
`readData` is not implemented for the VM as mentioned in the issue, but
`readDataStr` is, so that is used for `readStr` instead on the VM. We
could also just use it in general since it falls back to `readData`
anyway but it's kept the same otherwise for now.
Also where and why streams in general don't work in VM is now documented
on the top level `streams` module documentation.

refs #24032, split from #24036
Conversion from variables of range types or base types of range types to
the other are now considered mutable for `var` params, similar to how
distinct types are mutable when converted to their base type or vice
versa. There are 2 main differences:
1. Conversions from base types to range types need to emit
`nkChckRange`, which is not generated for things like tuple/object
fields.
2. Range types can still correspond to different types in the backend
when nested in other types, such as `set[range[3..5]]` vs
`set[range[0..5]]`.
Since the convertibility check for `var` params and a check whether to
emit a no-op for `nkConv` (and now also `nkChckRange`) so that the
output is still addressable both use `sameType`, we accomplish this by
adding a new flag to `sameType` that ignores range types, but only when
they're not nested in other types. The implementation for this might be
flawed, I didn't include children of some metatypes as "nested in other
types", but stuff like `tyGenericInst` params are respected.

fixes #24044
When matching a `tyFromExpr` against a `static` generic parameter,
`paramTypesMatch` tries to evaluate it as a constant expression, which
causes a segfault in the case of #24044. In #24005 a consequence of the
same behavior was an issue where `nkStaticExpr` was created for
`tyFromExpr` which made it not instantiate, so only the generation of
`nkStaticExpr` was disabled. Instead we now just completely ignore
`tyFromExpr` matching a `static` generic parameter in generic contexts
and keep it untouched.

fixes #24048
Generic lambdas get instantiated via `replaceTypesInBody` which calls
`replaceTypeVarsN` on the body of the lambda. This body can contain sym
nodes of gensym symbols generated by macros, which have `nil` type. But
a piece of code in `replaceTypeVarsN` checks whether the type of a
symbol is equal to `void` without checking if it's `nil` first, which
causes a segfault. Now it also checks that the type of the symbol isn't
`nil` for it to be `void`.

fixes #16376
The way the compiler handled generic proc instantiations in calls (like
`foo[int](...)`) up to this point was to instantiate `foo[int]`, create
a symbol for the instantiated proc (or a symchoice for multiple procs
excluding ones with mismatching generic param counts), then perform
overload resolution on this symbol/symchoice. The exception to this was
when the called symbol was already a symchoice node, in which case it
wasn't instantiated and overloading was called directly ([these
lines](https://github.com/nim-lang/Nim/blob/b7b1313d21deb687adab2b4a162e716ba561a26b/compiler/semexprs.nim#L3366-L3371)).
This has several problems:
* Templates and macros can't create instantiated symbols, so they
couldn't participate in overloaded explicit generic instantiations,
causing the issue #16376.
* Every single proc that can be instantiated with the given generic
params is fully instantiated including the body. #9997 is about this but
isn't fixed here since the instantiation isn't in a call.
The way overload resolution handles explicit instantiations by itself is
also buggy:
* It doesn't check constraints.
* It allows only partially providing the generic parameters, which makes
sense for implicit generics, but can cause ambiguity in overloading.
Here is how this PR deals with these problems:
* Overload resolution now always handles explicit generic instantiations
in calls, in `initCandidate`, as long as the symbol resolves to a
routine symbol.
* Overload resolution now checks the generic params for constraints and
correct parameter count (ignoring implicit params). If these don't
match, the entire overload is considered as not matching and not
instantiated.
* Special error messages are added for mismatching/missing/extra generic
params. This is almost all of the diff in `semcall`.
* Procs with matching generic parameters now instantiate only the type
of the signature in overload resolution, not the proc itself, which also
works for templates and macros.
Unfortunately we can't entirely remove instantiations because overload
resolution can't handle some cases with uninstantiated types even though
it's resolved in the binding (see the last 2 blocks in
`texplicitgenerics`). There are also some instantiation issues with
default params that #24005 didn't fix but I didn't want this to become
the 3rd huge generics PR in a row so I didn't dive too deep into trying
to fix them. There is still a minor instantiation fix in `semtypinst`
though for subscripts in calls.
Additional changes:
* Overloading of `[]` wasn't documented properly, it somewhat is now
because we need to mention the limitation that it can't be done for
generic procs/types.
* Tests can now enable the new type mismatch errors with just
`-d:testsConciseTypeMismatch` in the command.

fixes #24041
`when` statements in generic object types normally just leave their
conditions as expressions and still typecheck their branch bodies.
Instead of this, when the condition can be evaluated as a constant as
well as the ones before it and it resolves to `true`, it now uses the
body of that branch without typechecking the remaining ones.

Removes some noise from the bug report issue template so people who
aren't familiar can submit issues with less friction. Some of these
might be a bit subjective, feel free to call out any nitpicky parts, I
didn't want to rewrite entirely. Mostly fixed typos & language issues,
other than that:
* Just "detailed information", no need to say "descriptive", and changed
"reproducible code and detailed information" to "or detailed
information" because code is good enough
* Simplified description label, mention code example can go there
* Changed "Possible Solution" to "Known Workarounds" because it's what
issue authors are more likely to know (and usually write anyway) and is
more useful to most readers.
* Doc link for "rebuilding the compiler" was broken, replaced it with
mentioning choosenim, nightlies and building a temp compiler which is
hopefully less offputting
Weird looking preview
[here](https://github.com/metagn/Nim/blob/issue-templates/.github/ISSUE_TEMPLATE/bug_report.yml)
Just to complain: Github issue forms have some problems themselves,
there's no option to disable the "No response" text when an optional
area is unfilled, and the textboxes are really small at least on Firefox
(though you can expand them). The alternative, issue templates, isn't
much better. Github also hides the ability to open a blank issue in a
text link in a small line after all the issue form buttons, I'm guessing
this is intentional for repositories which don't want blank issues but
we don't have such a problem. Worst comes to worst we can add a button
for a minimal/empty issue template.

fixes #12539, refs #21636
`evalInclude` now uses `getPIdent` to check if a symbol isn't `/`
anymore instead of assuming it's an ident, which it's not when used in
templates. Also it just checks if the symbol is `as` now, because there
are other infix operators that could be used like `/../`.
It also works with prefix operators now by copying what was done in
#21636.

fixes #15314, fixes #24002
The OpenSym behavior first added to generics in #23091 now also applies
to templates, since templates can also capture symbols that are meant to
be replaced by local symbols if the context imports symbols with the
same name, as in the issue #24002. The experimental switch
`templateOpenSym` is added to enable this behavior for templates only,
and the experimental switch `openSym` is added to enable it for both
templates and generics, and the documentation now mainly mentions this
switch.
Additionally the logic for `nkOpenSymChoice` nodes that were previously
wrapped in `nkOpenSym` now apply to all `nkOpenSymChoice` nodes, and so
these nodes aren't wrapped in `nkOpenSym` anymore. This means
`nkOpenSym` can only have children of kind `nkSym` again, so it is more
in line with the structure of symchoice nodes. As for why they aren't
merged with `nkOpenSymChoice` nodes yet, we need some way to signal that
the node shouldn't become ambiguous if other options exist at
instantiation time, we already captured a symbol at the beginning and
another symbol can only replace it if it's closer in scope and
unambiguous.

updated version of #22193
After #22029 and the followups #23983 and #24005 which fixed issues with
it, `tyFromExpr` no longer match any proc params in generic type bodies
but delay all non-matching calls until the type is instantiated.
Previously the mechanism `fauxMatch` was used to pretend that any
failing match against `tyFromExpr` actually matched, but prevented the
instantiation of the type until later.
Since this mechanism is not needed anymore for `tyFromExpr`, it is now
only used for `tyError` to prevent cascading errors and changed to a
bool field for simplicity. A change in `semtypes` was also needed to
prevent calling `fitNode` on default param values resolving to type
`tyFromExpr` in generic procs for params with non-generic types, as this
would try to coerce the expression into a concrete type when it can't be
instantiated yet.
The aliases `tyProxy` and `tyUnknown` for `tyError` and `tyFromExpr` are
also removed for uniformity.

int types (#24017)
This is a very niche case encountered in #24012, where an int literal
got a `range` type as a result of a generic instantiation (in
`tgenericcomputedrange`), I can't think of another test case. The base
type of the range being `int` made it match `int` with `isSubrange` as
in the first `if` branch, but other int types like `int32` matched with
`isFromIntLit` which is a better match.
Instead, int literals with range type now:
1. match their base type with `isFromIntLit`,
2. don't match other int types with `isFromIntLit`, instead giving
`isConvertible` as in the last `if` branch in `handleRange`.

#8551, fixes #11112, fixes #20027, fixes #22647, refs #23854 and #23855
(remaining issue fixed), refs #8545 (works properly now with
`cast[static[bool]]` changed to `cast[bool]`), refs #22342 and #22607
(disabled tests added), succeeds #23194
Parameter and return type nodes in generic procs now undergo the same
`inGenericContext` treatment that nodes in generic type bodies do. This
allows many of the fixes in #22029 and followups to also apply to
generic proc signatures. Like #23983 however this needs some more
compiler fixes, but this time mostly in `sigmatch` and type
instantiations.
1. `tryReadingGenericParam` no longer treats `tyCompositeTypeClass` like
a concrete type anymore, so expressions like `Foo.T` where `Foo` is a
generic type don't look for a parameter of `Foo` in non-generic code
anymore. It also doesn't generate `tyFromExpr` in non-generic code for
any generic LHS. This is to handle a very specific case in `asyncmacro`
which used `FutureVar.astToStr` where `FutureVar` is generic.
2. The `tryResolvingStaticExpr` call when matching `tyFromExpr` in
sigmatch now doesn't consider call nodes in general unresolved, only
nodes with `tyFromExpr` type, which is emitted on unresolved expressions
by increasing `c.inGenericContext`. `c.inGenericContext == 0` is also
now required to attempt instantiating `tyFromExpr`. So matching against
`tyFromExpr` in proc signatures works in general now, but I'm
speculating it depends on constant folding in `semExpr` for statics to
match against it properly.
3. `paramTypesMatch` now doesn't try to change nodes with `tyFromExpr`
type into `tyStatic` type when fitting to a static type, because it
doesn't need to, they'll be handled the same way (this was a workaround
in place of the static type instantiation changes, only one of the
fields in the #22647 test doesn't work with it).
4. `tyStatic` matching now uses `inferStaticParam` instead of just range
type matching, so `Foo[N div 2]` can infer `N` in the same way `array[N
div 2, int]` can. `inferStaticParam` also disabled itself if the
inferred static param type already had a node, but `makeStaticExpr`
generates static types with unresolved nodes, so we only disable it if
it also doesn't have a binding. This might not work very well but the
static type instantiation changes should really lower the amount of
cases where it's encountered.
5. Static types now undergo type instantiation. Previously the branch
for `tyStatic` in `semtypinst` was a no-op, now it acts similarly to
instantiating any other type with the following differences:
- Other types only need instantiation if `containsGenericType` is true,
static types also get instantiated if their value node isn't a literal
node. Ideally any value node that is "already evaluated" should be
ignored, but I'm not sure of a better way to check this, maybe if
`evalConstExpr` emitted a flag. This is purely for optimization though.
- After instantiation, `semConstExpr` is called on the value node if
`not cl.allowMetaTypes` and the type isn't literally a `static` type.
Then the type of the node is set to the base type of the static type to
deal with `semConstExpr` stripping abstract types.
We need to do this because calls like `foo(N)` where `N` is `static int`
and `foo`'s first parameter is just `int` do not generate `tyFromExpr`,
they are fully typed and so `makeStaticExpr` is called on them, giving a
static type with an unresolved node.

types in symchoices (#23997)
fixes #23898, supersedes #23966 and #23990
Since #20631 ambiguous type symbols in templates are rejected outright,
now we generate a symchoice for type nodes if they're ambiguous, a
generalization of what was done in #22375. This is done for generics as
well. Symchoices also handle type symbols better now, ensuring their
type is a `typedesc` type; this probably isn't necessary for everything
to work but it makes the logic more robust.
Similar to #23989, we have to prepare for the fact that ambiguous type
symbols behave differently than normal type symbols and either error
normally or relegate to other routine symbols if the symbol is being
called. Generating a symchoice emulates this behavior, `semExpr` will
find the type symbol first, but since the symchoice has other symbols,
it will count as an ambiguous type symbol.
I know it seems spammy to carry around an ambiguity flag everywhere, but
in the future when we have something like #23104 we could just always
generate a symchoice, and the symchoice itself would carry the info of
whether the first symbol was ambiguous. But this could harm compiler
performance/memory use, it might be better to generate it only when we
have to, which in the case of type symbols is only when they're
ambiguous.

Notes that `cast[ref](...)` is excluded because we need to keep the ref
alive if the parameter is something with pointer types (e.g.
`cast[ref](pointer)`or `cast[ref](makePointer(...))`)

fixes #21258
When a generic proc is instantiated, if one of the default values
doesn't match the type of the parameter, `seminst` sets the default
parameter node to an `nkEmpty` node with `tyError` type. `sigmatch`
checks for this to give an error message if the default param is
actually used, but only while actively matching the proc signature,
before the proc is even instantiated. The error message also gives very
little information.
Now, we check for this in `updateDefaultParams` at the end of
`semResolvedCall`, after the proc has been instantiated. The `nkEmpty`
node also is given the original mismatching type instead rather than
`tyError`, only setting `tyError` after erroring to prevent cascading
errors. The error message is changed to the standard type mismatch error
also giving the instantiation info of the routine.

fixes #19737
As in the diff, `semResolvedCall` sets the return type of a call to a
proc to the type of the call. But in the case of the [subscript
magic](https://nim-lang.org/docs/system.html#%5B%5D%2CT%2CI), this type
is the first generic param which is also supposed to be the type of the
first argument, but this is invalid, the correct type is the element
type eventually given by `semSubscript`. Some lines above also [prevent
the subscript magics from instantiating their
params](https://github.com/nim-lang/Nim/blob/dda638c1ba985a77eac3c7518138992521884172/compiler/semcall.nim#L699)
so this type ends up being an unresolved generic param.
Since the type of the node is not `nil`, `prepareOperand` doesn't try to
type it again, and this unresolved generic param type ends up being the
final type of the node. To prevent this, we just never set the type of
the node if we encountered a subscript magic.
Maybe we could also rename the generic parameters of the subscript
magics to stuff like `DummyT`, `DummyI` if we want this to be easier to
debug in the future.

fixes #23998
In `fitNode` the first symbol of a symchoice that expects an enum type
with the same enum type is given as the result of the `fitNode`. But
`getConstExpr` is also called on it, which will return a `nil` node for
nodes that aren't constant but have the enum type, like variables or
proc parameters. Instead we just return the node directly since it's
already typed.
Normally, this `if` branch in `fitNode` shouldn't exist since
`paramTypesMatch` handles it, but the way pure enum symbols work makes
it really impractical to check their ambiguity, which `paramTypesMatch`
won't like. If it causes problems for regular enums we can restrict this
branch to just pure enums until they are hopefully eventually removed.

fixes #23893
When type symbols are ambiguous, calls to them aren't allowed to be type
conversions and only routine symbols are considered instead. But the
compiler doesn't acknowledge that qualified symbols can be ambiguous,
`qualifiedLookUp` directly tries to access the identifier from the
module string table. Now it checks the relevant symbol iterators for any
symbol after the first received symbol, in which case the symbol is
considered ambiguous. `nkDotExpr` is also included in the whitelist of
node kinds for ambiguous type symbols (not entirely sure why this
exists, it's missing `nkAccQuoted` as well).

fixes #23406, closes #23854, closes #23855 (test code of both compiles
but separate issue exists), refs #23432, follows #23411
In generic bodies, previously all regular `nkCall` nodes like `foo(a,
b)` were directly treated as generic statements and delayed immediately,
but other call kinds like `a.foo(b)`, `foo a, b` etc underwent
typechecking before making sure they have to be delayed, as implemented
in #22029. Since the behavior for `nkCall` was slightly buggy (as in
#23406), the behavior for all call kinds is now to call `semTypeExpr`.
However the vast majority of calls in generic bodies out there are
`nkCall`, and while there isn't a difference in the expected behavior,
this exposes many issues with the implementation started in #22029 given
how much more code uses it now. The portion of these issues that CI has
caught are fixed in this PR but it's possible there are more.
1. Deref expressions, dot expressions and calls to dot expressions now
handle and propagate `tyFromExpr`. This is most of the changes in
`semexprs`.
2. For deref expressions to work in `typeof`, a new type flag
`tfNonConstExpr` is added for `tyFromExpr` that calls `semExprWithType`
with `efInTypeof` on the expression instead of `semConstExpr`. This type
flag is set for every `tyFromExpr` type of a node that `prepareNode`
encounters, so that the node itself isn't evaluated at compile time when
just trying to get the type of the node.
3. Unresolved `static` types matching `static` parameters is now treated
the same as unresolved generic types matching `typedesc` parameters in
generic type bodies, it causes a failed match which delays the call
instantiation.
4. `typedesc` parameters now reject all types containing unresolved
generic types like `seq[T]`, not just generic param types by themselves.
(using `containsGenericType`)
5. `semgnrc` now doesn't leave generic param symbols it encounters in
generic type contexts as just identifiers, and instead turns them into
symbol nodes. Normally in generic procs, this isn't a problem since the
generic param symbols will be provided again at instantiation time (and
in fact creating symbol nodes causes issues since `seminst` doesn't
actually instantiate proc body node types).
But generic types can try to be instantiated early in `sigmatch` which
will give an undeclared identifier error when the param is not provided.
Nodes in generic types (specifically in `tyFromExpr` which should be the
only use for `semGenericStmt`) undergo full generic type instantiation
with `prepareNode`, so there is no issue of these symbols remaining as
uninstantiated generic types.
6. `prepareNode` now has more logic for which nodes to avoid
instantiating.
Subscripts and subscripts turned into calls to `[]` by `semgnrc` need to
avoid instantiating the first operand, since it may be a generic body
type like `Generic` in an expression like `Generic[int]`.
Dot expressions cannot instantiate their RHS as it may be a generic proc
symbol or even an undeclared identifier for generic param fields, but
have to instantiate their LHS, so calls and subscripts need to still
instantiate their first node if it's a dot expression.
This logic still isn't perfect and needs the same level of detail as in
`semexprs` for which nodes can be left as "untyped" for overloading/dot
exprs/subscripts to handle, but should handle the majority of cases.
Also the `efDetermineType` requirement for which calls become
`tyFromExpr` is removed and as a result `efDetermineType` is entirely
unused again.

fixes #19848
Not sure why this wasn't the case already. The `if cl.allowMetaTypes:
return` line below for `tyFromExpr` [was added 10 years
ago](https://github.com/nim-lang/Nim/commit/d5798b43dec547f372eb49d5a8848a9970b12260).
Hopefully it was just negligence?
