I remember doing tests of things like that and finding that not
only did it not make a difference to performance, ldc produced
near-identical asm either way.
Then let's not complicate Phobos please. I'm really no friend of
special semantics for `step == 0` and stuff like that. Let's keep
code as readable and simple as possible, especially in the
standard libraries, and let the compilers do their job at
optimizing low-level stuff for release builds.
More templates surely impact compilation speed, and that's where
DMD shines.
