Ranges

[danilopedraza]

I want a special syntax to specify a range. Something like this:

(1..3).reduce((acc, cur) -> acc + cur) # 3

Notice that a..b includes a and excludes b.

I think it would be nice if ranges went in both ways: from left to right or from right to left, depending on its ends. If a < b:

• a..a: nothing to iterate over
• a..b: a standard range: a, a + 1. ..., b - 1
• b..a: an inverted range: b, b - 1, ... a (it could be a + 1 for symmetry, but I like it more this way)

Right now this is enough.
