Except that doesn't work unless you use something like the autosuper
metaclass trick from test_descr.py (since the class A does not yet
exist where I put that super call).  And autosuper has a comment that
it "only works for dynamic classes" -- not sure that I understand what
"dynamic" means there.

In case you haven't guessed by now, I've only used two-arg super in my
own code.
