It can certainly be done (c.f. ChinesePython -
http://www.chinesepython.org/cgi_bin/cgb.cgi/english/english.html),
but I know of no framework that simplifies the task. Essentially, you
just have to manually modify Python's parser by swapping out the
english for the other language (and if you want to mess with the basic
types' names, their name definitions somewhere else too). There also
might be encoding issues to deal with.

Cheers,
Chris
