Not the person you’re asking, but basically anything that needs to happen after the initial parsing stage. So you convert your raw text into an AST, but there’s usually some processing you need to do after that.
Maybe you need to optimize the data, maybe you need to do some error checking. Lots of code is syntactically valid but not semantically valid, and usually those semantic errors will persist into the AST (in my limited experience).
