I may be totally off base here (and I thought hard about this before posting), but I don't see a use case for reflecting on anything other than the Class. Feel free to smack me if I'm wrong.
When you call describeType() on an instance, it leaves out static members of the Class, which I can't see being desirable if we're caching the results.
For what it's worth, agree that the implementation of the method is "different" than what the method describes, but only because this impl is the superior way of reflecting on the type.
