This code compiles, because the [0,0] dynamic array literal casts implicitly to
int[2]:


int[2] foo() {
    return [0, 0]; // OK
}
void main() {}


And of course this too compiles:


int[2] bar() {
    int[2] ab;
    return (true) ? ab : ab; // OK
}
void main() {}



But currently this code doesn't compile:


int[2] spam() {
    int[2] ab;
    return (true) ? ab : [0, 0]; // Error
}
void main() {}


DMD 2.058head:
test.d(3): Error: cannot implicitly convert expression (cast(int[])ab) of type
int[] to int[2u]

I think this isn't good.
