We're looking for: - Hints as to which python compiler would be best to work on. (The official Python compiler package seems very nice to work with actually...) - If there are any requests in the area of optimization that we could have a look at Even though the PEP has been rejected, I do like the idea of optimising chains of if...elif: http://www.python.org/dev/peps/pep-0275/

As a side note: Cython does this optimisation and translates a series of if-else statements (as well as "or" expressions) into C switch statements. The speedup is pretty impressive at times.
