-// Regression test for #53570. Here, we need to propagate that `T: 'a`
-// but in some versions of NLL we were propagating a stronger
-// requirement that `T: 'static`. This arose because we actually had
-// to propagate both that `T: 'a` but also `T: 'b` where `'b` is the
-// higher-ranked lifetime that appears in the type of the closure
-// parameter `x` -- since `'b` cannot be expressed in the caller's
-// space, that got promoted th `'static`.
-//
-// check-pass
