By the way, how much faster is cdecimal? 72x or 80x? http://docs.python.org/dev/whatsnew/3.3.html#decimal

Seconded.  This is the kind of stuff that will make 3.3 the most awesomest 3.x release ever (and hopefully convince people that it does make sense to port)... Thanks! For cdecimal specifically I have the impression that 3.x is already used in the financial community, where web framework dependencies aren't an issue. On the web side, there seems to be a huge interest in speeding up database accesses, so let me evangelize again: Database applications using decimal will run 12x faster in 3.3. Stefan Krah
