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++.

Hand-written C++ Code

Includes OS bindings. Small C++ files like cpp/osh_arith_parse.{cc,h} correspond to larger Python files like osh/arith_parse.py.
