ANTLR is a great tool. Unfortunately - although trying hard to change
it this morning in order to suppress keyword lookup in certain places -
I don't know anything about the interface between Python and its
parser. Is there some documentation on that (or can some divine deity
guide me with a few hints where to look in Parser/*)?

Which compilers/platforms would this affect? VC++/Windows
won't be a problem, I guess; gcc mostly comes with g++,
but not always as a default. Probably more problematic.
