Ayaz Hafiz	ecab8fa25a	Make sure self-recursive checks only happen after typechecking ... Programs like ``` after : ({} -> a), ({} -> b) -> ({} -> b) fx = after (\{} -> {}) \{} -> if Bool.true then fx {} else {} ``` are legal because they always decay to functions, even if they may not look like functions syntactically. Rather than using a syntactic check to check for illegally-recursive functions, we should only perform such checks after we know the types of values. Closes #4291	2022-10-17 09:59:32 -05:00
