Since the language we have does have multiple inheritance, let's
use it to implement mixins. My point was that even if Python had
been implemented without multiple inheritance, it would have
been simple to implement mixins, or by copying the methods,
or by dispatching with __getattr__. So, multiple inheritance
is giving us very little for the point of view of mixins; OTOH,
multiple inheritance is giving us a lot of headaches for
what concerns cooperative methods.
