Hard to find it, indeed.

Maybe, never been told of another one, do you think of javascript prototypes ? 
Well, there are no methods in this model, only functions.

I never saw the term "method" used for anything except for what it means for 
classes, and moreover, the class model, even if it's just an implementation, 
it's the one chosen by python.
For the common understanding of the model, IMHO, classes bind methods, 
instances bind functions.
