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?
