Ooh. I like that. That would have never occurred to me. :)
It felt kind of clumsy when I ended up with it. I don't think it
shows my intent very well (repeat the range in reverse). I wish
Phobos had something like a mirror() range (i.e. chain(rng,
rng.retro())).

Does that compile for you? Failed for me with
v2.066-devel-d0f461a:

A regression?
I did it on dpaste which is using 2.065 so I suspect regression.

I had the same problem at one point. I will try to understand
when that happens.
Ali
I was getting the integers when I was using character literals
with repeat() rather than string literals.
