About implicit array cast

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() {}
test.d(3): Error: cannot implicitly convert expression (cast(int[])ab) of type int[] to int[2u]
Is this good?
Bye,
