Does Number hew too close to Foundation's NSNumber name?

`Arithmetic` provides a beautiful hook for grammar pedants: as a protocol name it ought to be pronounced as the adjective "arithMEtic" and not the noun "aRITHmetic". Complaining about that sounds like fun to me, but naming the protocol `Arithmetical` would avoid that issue if others disagree.
