***Parsing will aggregate any tokens within a function body or expression statement to an untyped Code AST.***

Everything is done in one pass for both the preprocessor directives and the rest of the language.

The parser performs no macro expansion as the scope of gencpp feature-set is to only support the preprocessor for the goal of having rudimentary awareness of preprocessor ***conditionals***, ***defines***, and ***includes***, and ***pragmas**.

Keywords kept from "Modern C++":

* constexpr : Great to store compile-time constants.

* consteval : Technically fine, need to make sure to execute in moderation.
|

* constinit : Better than constexpr at doing its job, however, its only c++ 20.
