D2 supports the interval syntax in the foreach:
foreach (i; 1..1000) {...}
Such intervals are useful in a very large number of situations. So,
with the new Range support, it may be useful to allow the interval
syntax to be used in other contexts as well.
So x..y may become a first-class lazy interval from x to y-1, that can
be passed to functions too, etc, and not just used into foreach (the
compiler can recognize it, and often optimize it away in many
situations, replacing it with a normal for() loop).
I agree that having first-class intervals in the language would make it
better, especially when you want to pass intervals as function arguments.
I'm having trouble understanding what's wrong with the good old data
types and functions.
