check `FnDef` return type for WF better version of #106807, fixes #84533 (mostly). It's not perfect given that we still ignore WF requirements involving bound regions but I wasn't able to quickly write an example, so even if theoretically exploitable, it should be far harder to trigger. This is strictly more restrictive than checking the return type for WF as part of the builtin `FnDef: FnOnce` impl (#106807) and moving to this approach in the future will not break any code. ~~It also agrees with my theoretical view of how this should behave~~ r? types |
