I have just released version 0.9.13 of Shed Skin, a restricted-python to C++ transpiler. Shed Skin allows one to effectively convert (or transpile) pure Python code to highly optimized machine code. This comes at the cost though of having to conform to a seriously restricted subset of Python features/libraries. Programs currently also cannot be too large, although it is possible to generate extension modules, that can be used in larger programs.
The following screenshot is of a DOOM engine, that becomes more than 30 times faster after transpilation. The engine is compiled with Shed Skin, then imported in a larger program that uses Pygame for the UI (see also a before-after video).
Version 0.9.13 is the first version that was heavily improved by the use of AI (more specifically, Claude - thanks to Shakeeb for starting this). It was able to spot (and fix) many bugs, especially in the C++ backend, but also test gaps. It also helped to add support for many missing features in Python 3.15. We are now actually pretty close to full compatibility there, at least with regards to the supported modules and everything that is compatible with Shed Skin (no os.walk yet, for example, as it uses heterogenous tuples of length > 2, something we may fix for 0.9.14).
The use of AI should make it much easier to contribute as well. For example, if your program doesn't work, AI can minimize it and produce a useful bug report to submit to the project. It can even start to try and fix the problem, create new tests and so on. Or otherwise look for gaps/bugs to work on.
