I thought the reason the proposal got nowhere was because it's pretty
simple to define it yourself:

>>> class SliceHelper:
...     def __getitem__(self, slice):
...         return slice
...
>>> SH = SliceHelper()
>>> SH[1::3]
slice(1, None, 3)

Did I miss something significant about why this wasn't sufficient?
