Even a simpler code doesn't work:

     double[3] v1 = [1.0, 2.0, 3.0];
     double[3] v2 = [2.0, 3.0, 4.0];

     auto result = v1[0..$] + v2[0..$];

Error: Array operation v1[0LU..__dollar] + v2[0LU..__dollar] not implemented

The following doesn't work either:

     auto result = v1[] + v2[];
     auto result = v1 + v2;

dmd does not implement those features yet.
