Shed Skin – A (restricted) Python-to-C++ Compiler

The journey was:

- naive python solver: https://github.com/dgoffredo/wait-time/blob/master/solver.py

- "optimized" solver that ended up being slower due to more time spent in the python interpreter: https://github.com/dgoffredo/wait-time/blob/master/solver_op...

- used Shed Skin to speed up the python bits, but I don't recall whether I got it to integrate with the fsolve module (I doubt it in retrospect)

- rewrote it all in C++ templates using some professor's linpack port; MUCH faster: https://github.com/dgoffredo/hybrd/blob/d84013352797e61d449b...

Then I saw that they only just pivoted Python3. Nice. :)

> Some timings for the Shed Skin 'sieve' example (n=100000000) and several Python implementations/optimizers:

  cpython 3.10.6:     13.4 seconds
  cpython 3.11.0:     11.4
  nuitka 0.6.16:      11.4
  pypy 3.9.12:        5.8
  numba 0.56.4:       2.5
  shedskin (master):  1.9

It's about Python3 support for this Python-to-C++ compiler.

Not clear at a glance whether it's Python3 changes in the code or supporting Python3 to C++. I guess both.
