I am sure it is.

Advantages of a method over a function:
-- a method is a more natural way to query or manipulate objects;
-- a direct method call is faster than two-level call (len() => .__len__());
-- unnecessary cluttering of builtin namespace; the namespace should(1)
contains only really global functions (__import__(), eval(), etc.)
What are the advantages of a function over a method? What are
disadvantages of a direct .len() instead of .__len__()?
Footnote:
(1) I am a perfectionist and I partially disagree with "practicality beats
purity"; I would really love a small uncluttered builtin namespace in
Python.
