ints(), longs(), doubles() <was> Re: Ranges

[Brian Goetz]

There are two situations that give rise to ranges: math problems (which 
generally want closed ranges) and indexing (which generally wants open 
ranges.)  And its hard to satisfy both with one method.

One question is: should they be spelled the same way?  Would 
indexes(start, bound) and range(start, end) be better than having 
range(start, bound) and rangeClosed(start, end) ?
