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 -jJ _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
