This is both great to hear (ivar introspection available) and a little disappointing (method level not).  Basically, I would hope for at least enough to allow implementation of KVC - which would require the ability to find and invoke methods by name.

We already emit reflection data that describes the physical layouts of types, and once those formats are stabilized, building a library that interprets the metadata is additive (and could conceivably be done by a third party independent of the standard library). There may not be metadata for individual methods yet
