Ruby 2.2 and PHP 7 are faster than Python 2. Python 3 is slower than Python 2. Performance is a attractive feature. Python 3 lacks it.
That is not a fair statement to make about Python 3. It entirely depends on your workload whether it is faster or slower.

I hope that these API will create more optimizer projects than just fatoptimizer. For example, I expect more specialized optimizers like numba or pythran which are very efficient but more specific (ex: numeric computations) than fatoptimizer. Maybe not new optimizers, but just glue to existing static compilers (numba, pythran, cython, etc.).
> If there's anything I can do, let me know. :) Oh, they are a lot of things to do! My patches for PEP 509, 510 and 511 still need some love (reviews): http://bugs.python.org/issue26058 http://bugs.python.org/issue26098 http://bugs.python.org/issue26145 I'm finishing my patch adding ast.Constant. This one is less controversal, it has no impact on performance nor the Python semantics: http://bugs.python.org/issue26146 But these patches are boring C code. You may prefer to work on the funny fatoptimizer project which is written in pure Python: https://fatoptimizer.readthedocs.org/en/latest/ Victor
