Summary: itertools.getitem()
Initial Comment:
This patch adds itertools.getitem() which is basically equivalent to the
following python code:
_default = object()
def getitem(iterable, index, default=_default):
try:
return list(iterable)[index]
except IndexError:
if default is _default:
raise
return default
but without materializing the complete list. Negative indexes are supported too.
