[Python-Dev] quit() on the prompt

Ian reproposed:

    class Quitter(object):
         def __init__(self, name):
             self.name = name
         def __repr__(self):
             return 'Use %s() to exit' % self.name
         def __call__(self):
             raise SystemExit()

The one change I would suggest is the string used in repr.

Some of the objections to the current behavior boil down to
"If it knows what I mean, why didn't it do it?"  We probably
can't explain first-class callables in a short message, but
we could emphasize that it has to be *call*ed.  Perhaps

         def __repr__(self):
             return 'Calling %s() will exit python' % self.name
