> Why not index the slice type itself? slice[1:2]

I originally considered this and I personally really like this syntax, but I was concerned with ambiguity with the typing module

> The only question in my mind is what slice should do when given just a single index

I think some of the power of this concept comes from the fact that I can express a complicated indexer without worrying about how it desugars. I would personally prefer being able to have this return tuples and scalars so that the syntax is easier to explain.
