I like your idea of [i..j] alone meaning interval. After all, that's exactly 
the sense, no? And
(1) it solves the issue of [i..j:step] ambiguity
(2) which may even extend to slices: array[1..$:3]
But it's inconsistent with
    foreach (n; i..j) {}
We should have had this syntax from the start, or we face a backward 
incompatible change.
I would vote for it, but only because I don't have a big D code base ;-)
