So this seems to apply to member pointer types, pointer types, arrays and function types but I don't see coverage for the full set of paths in the tests. Can we please add more testing.

Erich also expressed some concern about breaking existing code due to eager instantiation. Can we make sure try to cover any change in behavior in the tests so reviewers can get a better idea of impact.
