I appreciate the work you are doing to improve D textual Input/Output.

Regarding lazy ranges, generally I prefer the textual output to give me hints
of what I have printed. So I'd like some difference between the textual
representation of this array:

[0, 1, 2]

And this range:

iota(3)

I think a simple way to tell them apart is to use a different separator.
Functional languages sometimes use the semicolon to separate list items, so I
think it's nice to print iota(3) like this:

[0; 1; 2]
