-// run-pass
-// This is a regression test for the ICE from issue #10846.
-//
-// The original issue causing the ICE: the LUB-computations during
-// type inference were encountering late-bound lifetimes, and
-// asserting that such lifetimes should have already been substituted
-// with a concrete lifetime.
-//
-// However, those encounters were occurring within the lexical scope
-// of the binding for the late-bound lifetime; that is, the late-bound
-// lifetimes were perfectly valid.  The core problem was that the type
-// folding code was over-zealously passing back all lifetimes when
-// doing region-folding, when really all clients of the region-folding
-// case only want to see FREE lifetime variables, not bound ones.
-
-// pretty-expanded FIXME #23616
