If you're talking about making it generate code for languages
that are very different from C, or for implementations other
than CPython, it would require major restructuring. There
isn't currently any such thing as a front and back end,
except in a very conceptual way. Code generation is done
by methods spread all over the parse tree. It would all
have to be rearranged to use a visitor pattern or something.
