While I give you props for the simplicity of this solution, it is rather useless in this case. Once again it's the 64 bit integer limit of Perl that would keep me from doing this. (Actually 63, because of the sign, but anyways) My number is quite a bit larger than the standard Perl scalar. (no pun intended.)
