++-- ends a block comment. Currently it must be at the start of a line.
Probably good enuf.

I would envision a built-in variable $CRASH$
If you wished to catch fatal errors you would assign
a function to it.
  $CRASH$ =3D routine_id ("CleanUp")
That way you could change (or eliminate) the cleanup
code as the program progresses.

I'll take a look at tk_mem.e  Dll interfaces follow such a consistent
pattern that its hard to believe they can't be automated better. Don't
know how though.

I am currently working on the interface to IUP  (a library - no
specific interpreter support). I really like IUP as a small and
simple GUI. So far buttons, toggles, checkboxes, radios, text,
lists, menus, and color selections work, with remarkably little
code.  I may attempt their 2D drawing library as well.

No, but I'm open to suggestion. They are quite a bit of
work though, and I'm not even sure about extract().
