I am no expert at optimizing D code, so this is a bit of a shot
in the dark, but does your speed improve at all if you replace:
this.data = new T[this.dim.size];
with:
this.data.length = this.dim.size
Why would that make a difference here? They're (almost) identical
are they not? Certainly the body of the work, the allocation
itself, is the same.
