Thanks for sharing your insights.

If you are interested in contributing more benchmarks to help python
compiler developers make performance optimizations based on
semi-realistic usecases, please check out this github repo:

https://github.com/numfocus/python-benchmarks

I think a python + numba and a cython implementation of an (averaged)
perceptron algorithm would be very interesting.

I share you conclusions:

- numba (and similar JIT compilers such as parakeet) is a game changer
for high performance Python dev
- it's still too early to consider it as production replacement for
cython (cryptic error messages, unsupported python constructs, API and
design still evolving...)
