it can be done, when the user passes more than one index
they will be combined into a tuple for you. also, there's
no need to just use integers :]

 >>> class K:
...     def __getitem__(self, args):
...             print 'GETITEM ARGS:', args
...
 >>> k=K()
 >>> k[1]
GETITEM ARGS: 1
 >>> k[1,2]
GETITEM ARGS: (1, 2)
 >>> k['bread', 'milk']
GETITEM ARGS: ('bread', 'milk')
