This is long overdue. Let's see if it gets me using traces more during
debugging.
Though perhaps I'm being too persnickety. These are all valid ways to
debug programs:
a) print directly to screen
b) log, and then dump the log on some condition
c) temporarily print selected log statements directly to screen
d) log, and then browse the log using the zoom interface
For a) to work we need to normally keep prints empty.
For b) to work the log needs to be of some manageable size, where it's
tractable to find interesting features.
d) is the ultimate weapon, but might be slow because it's interactive
c) seems like the ugly case. Should I be trying to avoid it altogether?
Let's try, and see if d) is useable when we want to do c). For simple
cases it's still totally acceptable to just print. If the prints get too
complex to parse, then we move to the zoom interface. Hopefully it'll be
easier because we have to spend less time getting the prints just so.
(Independent of all this, often the best way to make a log manageable so
any of the approaches works: distill the bad behavior down to a test.
But that leads to chicken-and-egg situations where you need to first
understand before you can distill.)

Another gotcha uncovered in the process of sorting out the previous
commit: I keep using eof() but forgetting that there are two other
states an istream can get into. Just never use eof().

Got that idea to work with a special-case for 'new'. Requires parsing
new's first ingredient, performing the replacement, and then turning it
back into a string. I didn't want to replace NEW with ALLOCATE right
here, because then it messes with my invariant that transform should
never see a naked ALLOCATE.
Layer 11 still not working, but everything else is. Let's clean up
before we diagnose the new breakage.

Yup, type ingredients were taking size 1 by default.

No, my idea was abortive. My new plan was to run no transforms for
generic recipes, and instead only run them on concrete specializations
as they're created.
The trouble with this approach is that new contains a type specification
in its ingredient which apparently needed to be transformed into an
allocate before specialization.
But no, how was that working? How was new computing size based on type
ingredients? It might have been wrong all along.

Commands run:
$ sed -i 's/\([^. (]*\)\.find(\([^)]*\)) != [^.]*\.end()/contains_key(\1, \2)/g' 0[^0]*cc
$ sed -i 's/\([^. (]*\)\.find(\([^)]*\)) == [^.]*\.end()/!contains_key(\1, \2)/g' 0[^0]*cc

I'm still seeing all sorts of failures in turning on layer 11 of edit/,
so I'm backing away and nailing down every culprit I run into. First up:
stop accidentally inserting empty objects into maps during lookups.
Commands run:
$ sed -i 's/\(Recipe_ordinal\|Recipe\|Type_ordinal\|Type\|Memory\)\[\([^]]*\)\] = \(.*\);/put(\1, \2, \3);/' 0[1-9]*
$ vi 075scenario_console.cc # manually fix up Memory[Memory[CONSOLE]]
$ sed -i 's/\(Memory\)\[\([^]]*\)\]/get_or_insert(\1, \2)/' 0[1-9]*
$ sed -i 's/\(Recipe_ordinal\|Type_ordinal\)\[\([^]]*\)\]/get(\1, \2)/' 0[1-9]*
$ sed -i 's/\(Recipe\|Type\)\[\([^]]*\)\]/get(\1, \2)/' 0[1-9]*
Now mu dies pretty quickly because of all the places I try to lookup a
missing value.

It was reading lines like this in scenarios:
-warn: f: error error
as:
-warn: f
which was causing them to be silently ignored.
Also found an insane preprocessor expansion from not parenthesizing
preprocessor arguments. SIZE(end+delim) worked even when end was an
integer, but it happily didn't ever get the wrong answer.

I've tried to update the Readme, but there are at least a couple of issues.
