Wrong IMO:

Python 2.2a1 (#21, Jul 18 2001, 04:25:46) [MSC 32 bit (Intel)] on win32
Type "copyright", "credits" or "license" for more information.
>>> class X:
...   def foo(*args): return args
...   goo = classmethod(foo)
...   global x
...   x = (foo, goo)
>>> print x
(<function foo at 007B786C>, <classmethod object at 007C7190>)
>>> print X.foo, X.goo
<unbound method X.foo> <bound method class.foo of <class __main__.X at 007B6664>>

The classmethod is created before the class is done,
it is converted into a method bound to the class
when you access it.
