The library API is a composition of code element constructors, and a non-standards-compliant single-pass C/C++ parser.
These build up a code AST to then serialize with a file builder, or can be traversed for staged-reflection of C/C++ code.
This code base attempts follow the [handmade philosophy](https://handmade.network/manifesto).
Its not meant to be a black box metaprogramming utility, it should be easy to intergrate into a user's project domain.
