It only has one use, and it's kind of ugly, so lets ditch it.

It's not clear to me why we should stop the first external interface in the parent chain.

iface.hasConcreteDescendent = True would be more Pythonic, I think.  You could
always make hasConcreteDescendent a property at some point in the future, if
you wanted to take some action when the value was set.

You can't have an external interface with a real interface parent, afaik.

hasConcreteDescendant is more pythonic, but elsewhere we've used the setFoo stuff.

It's only setIsConsequentialInterfaceOf, and setCallback (which should be called setIsCallback), afaict.  What if I volunteered to fix those two?

If a concrete interface inherits from an external interface, don't we just want to throw?

I'd be fine with that.  I'm mostly interested in consistency.

Actually, seIsConsequentialInterfaceOf(x) is not the same type of thing -- it's basically self.myConsequentialInterfaces.append(x).  So it's just the isCallback guy.

[Justin Lebar (not reading bugmail)]

And if we made isCallback a property, we'd have to change isDictionary, isInterface...I guess that's a job for later.  :)

Done.

We're using this for things now.  May want to revisit it later but it's not important.
