mycpp Translator

This prototype uses the MyPy frontend to translate statically-typed Python to C++. The generated code calls a small runtime which implements things like List[T], Dict[K, V], and Python's len().

Other Code Generators

In order to make Oils statically typed, we had to abandon Python reflection and use C++ source code generation instead. The lexer, flag definitions, and constants can be easily compiled to C++.

OSH (and common libraries)

This is the input to the translators, written in statically-typed Python. Note that bash is at least 140K lines of code, and OSH implements a large part of bash and more.
