Nope, that's a different check. If C derives from B derives from A, this
check allows either C.__init__ or B.__init__ to be called from A.__init__
with an instance of A. Greg wants B.__init__ to be OK here, but not
C.__init__ (C is not a direct base class of the one (A) where the method
(A.__init__) is defined). IOW, he wants a way to restrict __init__ calls to
immediate bases of the class from which the __init__ is invoked, to e.g.
prevent level-skipping under class rearrangement.
I posted some ugly code to address that, but think it's really a job for a
text editor and a pair of eyeballs <wink>.
