[Python-Dev] Python keywords (was Lockstep iteration - eureka !)

[Bill Tutt]

This is an alternative approach that we should certainly consider. We could
use ANTLR (www.antlr.org) as our parser generator, and have it generate Java
for JPython, and C++ for CPython.  This would be a good chunk of work, and
it's something I really don't have time to pursue. I don't even have time to
pursue the idea about moving keyword recognition into the lexer.

I'm just not sure if you want to bother introducing C++ into the Python
codebase solely to only have one parser for CPython and JPython.

Yet another reason why it would be nice to (eventually) merge the
parsing technology in CPython and JPython.
