This is almost an enhancement request.


int foo() {
    new int[][](1, 1);
    return 0;
}
enum _ = foo();
void main() {}


test.d(2): Error: Cannot interpret new int[][](1u,1u) at compile time
test.d(5): Error: cannot evaluate foo() at compile time


While this code works:

int foo() {
    int[][] m;
    m.length = 1;
    m[0].length = 1;
    assert(m == [[0]]);
    return 0;
}
enum _ = foo();
void main() {}
