dupping to allow vector operation?

Observe:
void main() {
int[3] a1 = [1, 3, 6];
int[] a2 = a1[] * 3; // line 3, Error
int[] a3 = a1.dup[] *= 3; // line 4, OK?
int[] a4 = (a1[] * 3).dup; // line 5, Error
}
Currently the operation in line 4 is accepted:
test.d(3,17): Error: array operation a1[] * 3 without destination
memory not allowed
test.d(5,18): Error: array operation a1[] * 3 without destination
memory not allowed
Is it a good idea to support something like line 5?
