Ranges redux

[Paul Sandoz]

Hi,

I think we reached consensus on:

- {Int, Long}String.range/rangeClosed for step of 1

IMO that seems good enough, and we can provide examples using map for step > 1 and descending ranges.

We have still to converge on DoubleStream.range, which might suggest no strong opinions or we lack the use-cases. There are some tricky edge-cases to deal with. I am very close to proposing we drop it...

Paul.
