I've been working on this slowly over several weeks, but it's too hard
to support 0 as the null value for addresses. I constantly have to add
exceptions for scalar value corresponding to an address type (now
occupying 2 locations). The final straw is the test for 'reload':
x:num <- reload text
'reload' returns an address. But there's no way to know that for
arbitrary instructions.
New plan: let's put this off for a bit and first create support for
literals. Then use 'null' instead of '0' for addresses everywhere. Then
it'll be easy to just change what 'null' means.

I no longer remember why we were disabling memory reclamation inside
sandboxes. Everything seems to be working. Just take it out.

Time to make my ad hoc commented out code fragments a first-class feature.

Properly support reloading lessons containing scenarios in edit/ and
sandbox/ apps.
I was so sure I tested this for commit 3724, but apparently not.

Support reloading the recipe side of the edit/ app when it includes type
abbreviations.
Thanks Ella Couch for reporting this problem.

Can't use type abbreviations inside 'memory-should-contain'.

Solution to a minor puzzle that came up during today's lesson with Ella:
some sandboxes were showing the address of text results, while others
were showing their contents. It took a while to realize that the
distinction lay in whether the sandbox was saving the results in a text
variable:
new [abc]
=> <some address>
x:text <- new [abc]
=> abc
It took *much* longer to realize why I couldn't make the first case work
like the second. Eventually I realized why: recipes were reclaiming
their results if they weren't 'escaping' -- that is, being saved in a
variable in the caller so they could be used later.
Any solution to this would be a hack, so I'm going to just leave it
alone. Type abbreviations should help minimize the extra typing needed
to get sandboxes to show text contents.

Deconstruct the tracing layer which had been an exception to our
includes-types-prototypes-globals-functions organization thus far.
To do this we predefine a few primitive globals before the types that
use them, and we pull some method definitions out of struct definitions
at the cost of having to manually write a couple of prototypes.
