Summary: Three __contains__ implementations

Initial Comment:

  Several classes in the stdlib implement dict-like
interfaces, but do not provide __contains__
definitions.  This is mentioned in PEP290 as a
"contra-indication" for updating code to use "k in d".
 The attached patch adds __contains__ implementations
for these stdlib classes.  As far as I can tell, this
brings all the dict-like classes in the stdlib "up to
date", so perhaps PEP290 should be updated as well.

Either mozilla or sf is screwing with me.  *grumble* 
There's no way I selected bisect.py for attachment.  Proper
file now attached.

The attached file has no ``__contains__`` definitions for anything.  Did you attach the correct file?
