[PATCH] D37104: [libc++] PR34298: Change std::function constructor and move assignment operator SFINAE checks to allow std::function with an incomplete return type

================
Comment at: test/libcxx/utilities/function.objects/func.require/incomplete_return_type.pass.cpp:17-19
+struct IncompleteReturnType {
+  std::function<IncompleteReturnType ()> fn;
+};
----------------
Would it make sense to also check that this struct is copy-constructible? As-is, whether this test tests anything is entirely dependent on what amount to implementation details of the constructor.
