I stand corrected. And I'm sure Guido knows why he did it
that way, but it adds to the complexity in the way Python
handles this stuff. I know SmallTalk has it simpler because
it only has to deal with single inheritance but the Python
super() implementation really, really feels flaky to me,
its one of the few Python features I don't enjoy using.

True, although it feels like that to the programmer.
But under the hood its different and potentially acts different.
Thanks for pointing that out - I'm gonna have to give it
some (more) thought. I keep trying to embrace super()
but every time I try I just find more issues with it. yek!
