there are many ways to skin a Python

I keep being undecided about what to use for writing Python extensions for those (few) parts where this very nice language happens to be too slow. I tried the handmade C way, C++ with sip, and now Pyrex.
For now seems to me that Pyrex should be the winner, but I've yet to give a try to boost::python that I was told is quite interesting (the scary part is that boost is huge and I'm using a compiler that's probably considered out ... VC++6).
