Summary: Mapping Type "in" and "not in" operators

Initial Comment:
According to the Python 2.1 documentation, Mapping 
Types support the "in" and "not in" operation.
http://www.python.org/doc/current/lib/typesmapping.html

But it doesn't work.  I tried the following:

>>> k = "key"
>>> a = { k : "value" }
>>> k in a
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: 'in' or 'not in' needs sequence right 
argument
