But the return value of hex() usually isn't an integer in the CPU-register sense!

And even when it is, plenty of languages can handle 64-bit integers on 32-bit hardware. There's no law that states that all variables must fit into a single CPU register. (How would strings ever work if that were the case?)

This kind of thing can be done portably. Therefore, it is legitimate to be puzzled about why Perl complains about it.
