But there's no need for a D compiler to optimize loops that just copy parts of an array into another array (and similar stuff), because in D you use slices for that - they're (probably) faster and easier to use. So IMHO it's fair to use slices where possible. (And they're a language feature and not just part of the library) Furthermore this particular benchmark is a "programming language benchmark" and not a compiler benchmark, so it's fair to use every feature of the language.
For example, a lot of effort is expended in C and Fortran compilers "reverse engineering" loops so they can be recompiled and optimized as vector operations. I don't see ever bothering with this in D compilers, as D offers a vector notation.
