Isn't mixing Perl- and Python-based solutions like mixing ammonia- and chlorine-based cleaners? They both work OK separately (though the first will smell much worse), but mix them together... And from someone named Guido, no less! For shame! (Then again, this week I wrote an interpreter implementing a substantial fraction of PostScript in Python, so my own sanity may be in question. :^)
