Well, I thought of doing this, but after looking up resolution order (sec
9.5.1 of the tutorial) I found that resolution is done "depth-first,
left-to-right",  In my example, that would have given [MySub, Sub, Base,
MyBase, Base], but, I checked, using mro(), and found that it was indeed
[MySub, Sub, MyBase, Base], just as I needed it.  (thanks for the mro() tip
- didn't know about that one).  Unless I've gone crosseyed (possible, it's
late), this is NOT depth-first, left-to-right.  So is the tutorial out of
date?
