I think you're forgetting what language you're talking about. Those are
numbers. After this statement:
$x = '345';
C<$x> is a number. I should hope it would be treated as one during
multimethod dispatch.
However, I'm not saying this with authority. I'm just extrapolating.
If it's not correct, I'd appreciate that someone who knows correct me.
