bors 1e9dda77b5 Auto merge of #118120 - compiler-errors:closure-kind, r=lcnr ... Remove `PredicateKind::ClosureKind` We don't need the `ClosureKind` predicate kind -- instead, `Fn`-family trait goals are left as ambiguous, and we only need to make progress on `FnOnce` projection goals for inference purposes. This is similar to how we do confirmation of `Fn`-family trait and projection goals in the new trait solver, which also doesn't use the `ClosureKind` predicate. Some hacky logic is added in the second commit so that we can keep the error messages the same.		2023-11-22 21:09:01 +00:00
