Thanks.  BTW, I have found your direction on multmethods very helpful
generally (and I see the point of super() being unsafe all by itself...
it scares me too :-)).

Hmmm... I DO NOT like that (nor did I know it).  After all:

    Python 2.2.2 (#0, Oct 24 2002, 20:53:04) [EMX GCC 2.8.1] on os2emx
    >>> class A(object): pass
    ...
    >>> class B(object): pass
    ...
    >>> class C(A,B): pass
    ...
    >>> class D(B,C): pass
    ...
    >>>

Ah, that halcyon day of Oct 24, 2002...

Is there a (good) reason for this change, or could it be an artifact of
the alpha version?  I don't have 2.3 installed myself.

Yours, David...
