Several of those features apparently never did come back. The repeat
count never did (you can't multiply ranges now), and it occurs to me
that slicing a range that has a repeat count is intractable:
(range(3)*2)[1:5] should yield 1, 2, 0, 1, which can't be represented as
a range object. It also doesn't support comparison operations.
