This was precisely my example, because that's the way I implemented the
return warning stuff, by modifying the com_xxx routines.  I believe that's
the wrong way to go in the long run, and I see by the rest of your message
you feel the same way as well.  To the greatest extent possible, I think
this stuff should be implemented in Python.  (We may disagree on that
point.)  Being able to plug in new parse tree analysis/transformation
modules between parse tree creation and code generation could at least be
controlled from Python.

P.S. Something I just noticed: Since the node typedef (node.h) and the
macros that manipulate nodes are shared across multiple files shouldn't they
be named something slightly less likely to clash with other packages?
