That's the same risk with to!string(), yes? We aren't really 
losing anything by adding it.

Also this reminds me of the utter uselessness of the current 
behavior of "%s" and a pointer - it prints the address.

I think this should be simply disallowed. If you want that, you 
can use %x, and if you want it printed, that's where the new %z 
comes in.
