The gdc version, by contrast, inlines *everything*,
This could be why I've observed performance differentials in
dmd for doing some manual for loops rather than using the
stuff in std.algorithms.
Very likely, I'd say. IME dmd tends to give up inlining rather
easily. This is very much something that needs to improve,
since ranges in D are supposed to be a big selling point.
Wouldn't want them to perform poorly compared to hand-written
loops.
Yeah, ranges should ideally be a zero-cost abstraction, at least
in trivial cases.
