Chayim Refael Friedman 5f25ae3d1b Lay the foundation for diagnostics in ty lowering, and implement a first diagnostic ... The diagnostic implemented is a simple one (E0109). It serves as a test for the new foundation. This commit only implements diagnostics for type in bodies and body-carrying signatures; the next commit will include diagnostics in the rest of the things. Also fix one weird bug that was detected when implementing this that caused `Fn::(A, B) -> C` (which is a valid, if bizarre, alternative syntax to `Fn(A, B) -> C` to lower incorrectly. And also fix a maybe-bug where parentheses were sneaked into a code string needlessly; this was not detected until now because the parentheses were removed (by the make-AST family API), but with a change in this commit they are now inserted. So fix that too.		2024-12-04 14:22:56 +02:00
