promote placeholder bounds to 'static obligations In NLL, when we are promoting a bound out from a closure, if we have a requirement that `T: 'a` where `'a` is in a higher universe, we were previously ignoring that, which is totally wrong. We should be promoting those constraints to `'static`, since universes are not expressible across closure boundaries. 2022-06-30 14:26:17 +00:00			error[E0310]: the parameter type `T` may not live long enough
use spans in TypeTest rather than mir::Location Spans are independent of the body being borrow-checked, so they don't need remapping when promoting type-tests and they yield more specific error spans inside bodies of closures/inline consts. 2022-10-03 10:45:02 +00:00			`--> $DIR/issue-98693.rs:16:9`
