FWIW, someone (Bengt Richter perhaps) once suggested syntactic support differentiated from sequences but less awkward than a call to itertools.islice(). itertools.islice(someseq, lo, hi) would be rendered as someseq'[lo:hi].

Just to make sure I'm reading this right, the difference between sequence slicing and iterator slicing is a single-quote? IMVHO, that's pretty hard to read...

If we're really looking for a builtin, wouldn't it be better to go the route of getattr/setattr and have something like getslice that could operate on both lists and iterators? Then getslice(lst, lo, hi) would just be an alias for lst[lo:hi] and getslice(itr, lo, hi) would just be an alias for itertools.islice(itr, lo, hi)
