Usually an AST is needed that is void of all syntactic sugar, That’s how I’ve always see “AST” used, but not the following: yet can express the required data flows and dependencies so the trivial substitutions/replacements/caching and refactorings can be done at this level. Is what you describe some flavor of ‘augmented’ AST? Does that have a name other than AST?
