@Unknown What's the difference between your's and this:

class Foo(object):

    def _bar(self, baz):
        print "_bar, baz:", baz

    def __init__(self, bar):
        self.bar = self._bar
        self.baz = bar

    @classmethod
    def bar(cls, baz):
        print "bar, baz:", baz

In [1]: import foo

In [2]: f = foo.Foo(42)

In [3]: f.bar(1)
_bar, baz: 1

In [4]: foo.Foo.bar(1)
bar, baz: 1

In [5]: f.__class__.bar(1)
bar, baz: 1
