Summary: bug in use of __getattribute__ ?

Initial Comment:
hello, why it do not work:
class xx(object):
  def __getattribute__(self,name):
      tab = object.__getattribute__(self,'tab')
      return tab[name]
  def f(self,a):
      self.a=a
x=xx()
xx.tab={'f':xx.f}
x.f(3)
unbound method f() must be called with xx instance as
first argument (got int instance instead)

This is not a bug. x.f results (via getattribute) in xx.f,
which is an "unbound method" (a method of a class that does
not belong to a specific instance) and as such has no
knowledge of your instance "x".

Please post first comp.lang.python in the future, as such
things are almost always a programmer's mistake.

Closing as Invalid.
