What's the correct opEquals signature for structs?

If you have the int value 25, this is a true value, in C you are free to use it for its zero/nonzero quality. But if opEquals is required to return a bool, the value 25 has to become 1, this is not just a narrowing. This conversion requires one instruction, I think.
