Be careful, I think a syntax like: v[0, 1] v[0, 1, 2, 3] Is better left to index in 2D and 4D arrays. nD arrays can be quite important in a language like D. So the following may be better and more compatible with the future: v[0; 1; 2; 3] = v2[3; 2; 1; 0]; Or: v[(0,1,2,3)] = v2[(3,2,1,0)]; Or: v[[0,1,2,3]] = v2[[3,2,1,0]]; Bye, bearophile
