-// Regression test for #57639:
-//
-// In the move to universes, this test stopped working. The problem
-// was that when the trait solver was asked to prove `for<'a> T::Item:
-// Foo<'a>` as part of WF checking, it wound up "eagerly committing"
-// to the where clause, which says that `T::Item: Foo<'a>`, but it
-// should instead have been using the bound found in the trait
-// declaration. Pre-universe, this used to work out ok because we got
-// "eager errors" due to the leak check.
-//
-// See [this comment on GitHub][c] for more details.
-//
-// check-pass
-//
