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.
