// This would be wonderful to fold into a larger test, but I'm worried that
// trying to do so would perturb the original conditions that cause it to
// crash: deserializing a typealias (1) to an imported Objective-C type (2)
// that has a protocol (3) that refines another protocol (4) which causes us
// to load all extensions, including one defined in this file (5) in terms of
// the original typealias (1).
//
// It's probably best to just leave this test about that.
