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

Shed Skin restricted-Python-to-C++ compiler 0.9.6

I recently decided to sit down and finally port Shed Skin, an
experimental restricted-Python-to-C++ compiler in the works since
2005 or so, to Python3. Three painful months and a total diff of 50k
lines later, everything now works with Python3 (Shed Skin itself, and
all tests and examples..)

This does not mean that every Python3 feature is supported, but what
was there now at least works fine with Python3.. For example, unicode
is still restricted to 1-byte characters, and there is no support
(yet) for nice new features such as f-strings. Python2 support has
been dropped with the new release, and subsequent releases should add
support for various new Python3 features.

The following people have contributed along the way:

  * Johan Kristensen (large patch for moving from compiler.ast to
    ast, still on Python2)
  * Shakeeb Alireza (extension module support for Python3, ported
    many examples, improved OSX support, and various code cleanups)
  * Folkert van Heusden (some fixes on the C++ side, move to c++17)
  * Jeremie Roquet, Thomas Spura, Paul Boddie and others who kept
    doing maintenance on the project in my absence

I started work on the port after realizing that Shed Skin was being
removed from distributions, especially Debian, as it was still tied
to Python2, and I really want to keep Shed Skin in a working state if
possible.

So what about the future of the project? Not really sure, but I'm
happy to sit down again in a few months to prepare a new release. Any
feedback on what to support or improve would be very welcome!

For fun, here are screenshots of some of the Shed Skin example
programs (in total 75 working example programs can be found on the
github site):
