This code compiles:

void main() {
    import std.algorithm: map, sum;
    int[][][] mat;
    mat.map!(map!sum);
}



While this is wrong code:


void main() {
    import std.algorithm: map, sum;
    int[][] mat;
    mat.map!(map!sum);
}



But the mistake is caught by the linker instead of the dmd, dmd 2.066alpha:
