In effect, 2.6 forces you to have a common known base class *other*

You have to do that anyway if you want to make cooperative
calls to any method *other* that __init__.
I haven't found that to be an issue, actually, since there's usually
a base where the "bottom" version of those methods live, and anything
implementing those methods is going to inherit it via the mixin. The
problem is that for at least __init__ and __new__, 'object' *is* the
"bottom" -- and there may be more than one family of mixins that need
to call it.
