This isn't a very sane plan. The ~300 LOC example mini_grep (https://github.com/z-libs/Zen-C/blob/main/examples/tools/min...) compiles to a ~3.3k LOC monstrosity (https://pastebin.com/raw/6FBSpt1z). It's easier to rewrite the whole thing than going from the generated code.
At least for now, generated code shouldn't be considered something you're ever supposed to interact with.
