Lowering from the current MVP typed AST into the reusable HIR model.
Recursive-descent parser for the compiler-support MVP grammar.
Arena-backed ownership context for AST nodes.
Arena-backed ownership context for HIR nodes.
Lowers the MVP typed AST into HIR.
Recursive-descent parser that produces an AST in Compiler_Ast_Context.
Inference-oriented semantic pass for the MVP compiler front-end.
void analyze_module(const Compiler_Module *module)
