Why not? Isn't that exactly what a range is supposed to be good for?
It sounds like a bad idea to me... I can imagine ending up with a whole
pile of allocations of short ranges, and then people doing bunches of
range concatenations to re-assemble the buffer. That's a lot of
pointless allocation and memcopying. D's apis should discourage
inefficient usage like that.
I think ranges are here to avoid memcopying and pointless allocations.
