One way to achieve this is the decode the binary as both a string and
an integer, and then lug both around at the same time.

My guess is you wont win much by doing this. Of course, the string is
taking up some space, but lugging it around is still just a
pointer-pass. I wouldn't worry too much about it until it ends up
being a bottleneck.
