Slice literals are a logical next step, precedented by raw strings and
bytes.  slice= islice is too, precedented by range= xrange.

Does s[2:] evaluate to an infinity?  What is the natural meaning of
skipping finitely many terms at the head of an iterable?  itertools
can also grow 'skip(n=0)' and 'drop(step=3)' operations.
