The other reason is that explicitely using a self-reference for instances goes
along with the method of calling unbound class-methods, and allows one to
easily `fake' membership of an instance in a class.

Last I checked, everything in Python already was an object;)
Strings -are- objects--they just don't belong to a class or have any
properties/members/whateveryouwanttocallthem (some non-class--`top-level' I
suppose they should be called--objects do have members, like lists and
I rather like the var-name-subsitution that PERL and Ruby and some other
languages do (ie: $something="bar"; "foo$something" == "foobar"), because it
shortens code, and sometimes makes it much prettier (having stripped out all of
the `end string, use an operator, reference something, resume new string'
procedures); Python's %-replacement is nice, too, though a bit more lengthy.
One thing to remember: languages all have their strengths and weaknesses, and
-rarely- is a language best for -everything-.
(back on track with the start of the thread: yeah, the shortcut operators
wouldn't really work well with Pythonic `assingment'/name-binding and immutable
