Distinguishing attributes and methods

[MonkeeSage]

It seems that I've got a short-circuit somewhere here. I understand
that everything is an object and the the storage/lookup system is
object-agnostic, and that it is only the descriptors (or "tags" as I
called them generically) that determine how an attribute is bound,
whether it is bound at all, whether it is even callable, and so forth.
So, when I say that all callable attributes (or to be more precise,
all callable attributes bound to objects other than toplevel) are
"methods," what am I missing?

You said "the difference [between a callable attribute and a method]
is the specific implementation of the attribute's class"...but this
almost sounds like type-by-primitive (a method is a method when it
derives from a certain base class), or type-by-behavior (a method is a
method when it behaves in a certain way, e.g., responds in a certain
way to a query). Is this correct? Shouldn't it be type-by-capability/
interface--i.e., it implements the protocol of a callable, therefore,
formally, it is not meaningfully different from any other callable
(quacks like a duck and all)?

I guess what I'm asking is, in what way is a "method" (or "function")
semantically different from a home-brewed callable I concoct and bind
to an object (or toplevel)? What is the distinction that I'm missing?

Ps. wrt your last comment, isn't a class object in essence a factory
method?
