well mapper_args is args that go to the mapper. Its a little unclean
IMHO to reuse that same dict for declarative purposes. Id rather have
another attribute like __declarative_abstract__ = True or something like
that (ideas welcome).

yeah the class decorator can't really handle the PKs. the mapper wants
those when it starts up. as far as implementation this feature isn't on
my personal radar, so if you really want anytime soon you should provide a
patch, which I can of course help with.
