Thanks for the quick response, Jim. I've already updated the usage of
selfImplied to using the new registered() method.


We have one more problem, though: Apparently, __adapt__ methods on Interface
objects are no longer called during adaptation. This only happens when using
the C optimizations, and at first I thought this didn't matter, because I
was under the impression z.i didn't actually care about PEP 246, but then I
noticed that README.txt explicitly talks about PEP 246 __adapt__ support.
Now, if there is a method IFoo.__adapt__, and one calls IFoo(o), that method
will not be called when using the C optimizations, because the C
implementation of __call__ just directly calls the C implementation of
__adapt__ without looking it up as a method on the interface object.

Is this a bug?
