-// Regression test for an ICE that occurred with the universes code:
-//
-// The signature of the closure `|_|` was being inferred to
-// `exists<'r> fn(&'r u8)`. This should result in a type error since
-// the signature `for<'r> fn(&'r u8)` is required. However, due to a
-// bug in the type variable generalization code, the placeholder for
-// `'r` was leaking out into the writeback phase, causing an ICE.
