But then the code you linked to looks more like Go than Python... There
isn't going to be an easy win there -- either it's python or it's not, and
unless compilers like pypy catch on, the general performance for
python-looking code is never going to be better than cPython.
Profiling can help with the optimisation, but it would be nice to have a
pep8 style "warning line 32: missed type declaration" tool.
