I edited this code to work with ldc (D1) + Tango, and saw the Direct
and opApply cases generate identical code (inc, cmp, jne, with the loop
counter in a register) [1], so they're equally fast (modulo process
scheduling randomness).
Thank you for your timings. I think it shows my point: that by
prefering ranges over opApply we're just optimising around a deficiency
in DMD's optimizer.
I'm thinking... with proper inlining, perhaps we could take the notion
of ranges out of the compiler and just define a generic opApply in
std.range that use front, popFront, and empty. :-) Perhaps.
