Error quality of life: trailing ? missing on a ?? assignment does not give a nice error

[joshring]

module faults;
fault
    EXAMPLE,
    DOG_ATE_MY_HOMEWORK,
    MY_TEXTBOOK_CAUGHT_FIRE,
    DISTRACTED_BY_CAT_PICTURES;


module testing_v0_7;
import faults;
import std::io;

fn int main(String[] args)
{

	int? foo = faults::EXAMPLE?; // miss the trailing `?` here and get a nice error: `Error: You need to add a trailing '?' here to make this an optional.`


	if (catch foo)
	{
		foo = foo ?? faults::DISTRACTED_BY_CAT_PICTURES; // Not such a clear error: `Error: Cannot find a common type for 'int' and 'anyfault'.`
		io::printfn("foo = %s", foo)!!;
	}

	return 0;
}
