Summary: Add set.member() method

Initial Comment:
Right now, when I check membership in a set, the __in__ method just 
returns True/False if there is an object in the set that's == to the 
argument. I would like to have a member() method that returns the object 
in the set or raises KeyError if the argument is not in the set. This would 
be useful for interning and other cases where right now I'd use a 
degenerate dictionary where the keys and values are equal.

Moving to Feature Requests. Note that I do not think Raymond
will agree to this.
