Message 73077 - Python tracker

Here's a version with views from Python 3.0 for keys, values, and items 
:) .  I know that no one hear likes my particular implementation (though 
it offers more or less the full interface), but the Keys, Values, and 
Items classes in the following version are quite generic (they only 
require that the base class implement __iter__, _itervalues, and 
_iteritems), and reasonably optimized.  They could probably be moved 
into the generic dbm stuff and used by everyone.
