In 1.6, yes. In 1.5.2, overloading 'in' is not possible, except by
overloading __getitem__ -- the 'in' implementation for user classes and most
builtin types simply __getsitems__ until it finds a match or reaches
IndexError. In 1.6, it's possible to override it in both and provide a more
efficient implementation. (See 'Objects/rangeobject.c' for an example ;-)
