It's not a bug, it's a feature request. It doesn't really need to be able
to resolve the type because the parameter will never be used. Yes, I'm being
lazy, it's possible for me to be more careful about what I pass in. On the
other hand, I think others would appreciate the ability to be this lazy,
as well.
