Since I filed the bug, I should clarify that the primary reason I'm
using super-init is to avoid multiple construction of a shared base
(even if the base is just object, since I'd prefer not to rely on
object's initializer being a no-op). C++ ensures that virtual bases
are only constructed once, so there's no concern as to multiple
construction. Is there a Python pattern better than super-init that
provides the same guarantee?

(Apologies if this appears in the wrong place; I just joined the list
and I'm not seeing a way to participate in an existing thread.)
