// Regression test for issue #19499. Due to incorrect caching of trait
// results for closures with upvars whose types were not fully
// computed, this rather bizarre little program (along with many more
// reasonable examples) let to ambiguity errors about not being able
// to infer sufficient type information.
//@ pretty-expanded FIXME #23616
