Concatenating
Expand description

Within a syntactic trait ref, there may be multiple poly trait refs that are nested (under the associcated_type_bounds feature). The binders of the innner poly trait refs are extended from the outer poly trait refs and don’t increase the late bound depth. If you had T: for<'a> Foo<Bar: for<'b> Baz<'a, 'b>>, then the for<'b> scope would be Concatenating. This also used in trait refs in where clauses where we have two binders for<> T: for<> Foo (I’ve intentionally left out any lifetimes because they aren’t needed to show the two scopes). The inner for<> has a scope of Concatenating.
