I don't understand.

In a program like:

void main() {
    int[] a1 = [1];
    int[] a2 = [2];
    int[] a3;
    a3 = a1 + a2;
}

I think the compiler has to write an error message like:
test.d(5): Error: Array operator + not supported (have you forgotten the []?)

So this is more correct code:

void main() {
    int[] a1 = [1];
    int[] a2 = [2];
    int[] a3;
    a3[] = a1[] + a2[];
}

But array ops don't allocate memory, so the a3 array can't be filled. This
prints nothing:

import std.stdio: writeln;
void main() {
    int[] a1 = [1];
    int[] a2 = [2];
    int[] a3;
    a3[] = a1[] + a2[];
    writeln(a3);
}

This other error can be found at runtime...
