Untrue. My simple Scheme object system (125 lines incl. documentation)
supports multiple inheritance without classes. Maybe I should port that
to Python...

Linnaean categorization of objects is unnecessary ontological chaff. How
many times have people here had to advise newcomers not to inspect type
and instance relations of objects and just call the method?

That's impossible to ascertain objectively. Java and JavaScript
programmers (of all people!) routinely deal with closures.
