I adapted staticMap's implementation to two sets of arguments:

So I've got this implementation, but wonder if I can generalise 
the arg splitting portion rather than write it manually for each 
N?

```d
template staticMapN(size_t N, alias fun, args...) if (args.length 
% N == 0) {
  alias staticMapN = AliasSeq!();
  static foreach (i; 0 .. args.length / N)
    static if (N == 1)
      staticMapN = AliasSeq!(staticMapN, fun!(args));
    else static if (N == 2)
      staticMapN = AliasSeq!(staticMapN, fun!(args[0 .. $ / 
N][i], args[$ / N .. ($ / N) * 2][i]));
    else static if (N == 3)
      staticMapN = AliasSeq!(staticMapN, fun!(args[0 .. $ / 
N][i], args[$ / N .. ($ / N) * 2][i], args[($ / N) * 2 .. ($ / N) 
* 3][i]));
    // etc
}
