* is also an infix operator, and we seem to get along fine with that.

Regardless, I don't think it will work. How about if you have an array 
of ranges?
[10..20, 20..30, 30..40]

How do you write that type?

This doesn't work:
int..int[]
Because, to me anyways, this translates to:
range!(int, int[])


Using .. should work for literals. All that is really needed is changing 
the precedence of the operator.

Currently, writing this:
x = 0 .. 10
translates to:
(x = 0) .. 10

I think the precedence fits best somewhere between + - and =. This way, 
we can write both:
x = 0 .. 10
arr[0 .. $ - 1]
