Code that uses the unrecommended practice of mixing int and uint with 
size_t everywhere will be indeed difficult to port to 64 bits. But 
that's a problem with the code, and giving that unrecommended practice 
legitimacy by making it look good is aiming at the wrong target.

Use size_t for sizes and it's golden. You can't go wrong. On the rare 
occasions when you want to store arrays of indexes, do the cast by hand, 
don't ask the standard library to give it a nice face by making the 
assumption for you.
