Summary: 'in' and 'not in' won't work for dict

Initial Comment:
In spite of what docs say.
(They say : "Equivalent to <not> a.has_key(k)")
but:
>>> 0 in {}
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
TypeError: 'in' or 'not in' needs sequence right argument

Which version of Python are you using?  This doesn't work 
in any released final version of Python -- it's a new-in-
2.2 feature (which hasn't been released yet).

Assigning to Fred because I seem to recall that the docs 
for this snuck out early by mistake.
