I have tried it. (Had to edit the Makefile by hand, because
"make -f Makefile.pre.in boot" did not produce a valid Makefile,
but I did manage to build and run the example.)  The problem is,
the Flex file (and Yacc file) is compiled into C, and then into
a shared lib. This means I must use C code in the Flex file.

What I want is something that lets me call arbitrary Python code
from the lexer. Ideal would be to have a version of Flex that
produces a Python file instead of a C file. I have kept looking,
and I think I found what I was looking for: PyLly, which is part
of PyGgy. http://www.lava.net/~newsham/pyggy/
