Doing the armchair code reviewer without context is easy but my guess
would be that the old style library classes were written long before
the new style ones (perhaps even before the latter were introduced)
and/or written independently by different developers/groups, without
any plan to mix the two in the future. Also remember that up to 2.4
even the standard exception classes were old-style so it's not safe to
assume that you only have new style classes to worry about when the
very standard library includes lots of legacy code.
