Deflection.get()

The Deflection methods check to see that the declaring class is also
public before forwarding the invocation. My old reflection API
addressed this issue by filtering out public members declared by
non-public classes. It did this by finding the overridden method in
the public super type. Since we couldn't reach consensus on the
behaviour of this reflection API, I addressed this issue in the
Deflection implementation.
