By the way, are you willing to divulge what you're using this
functionality for?  When trying to hack out the API for int.to_bytes
and int.from_bytes on the mailing list and bug tracker, some of the
discussion about use-cases seemed a little too much like guesswork;
I'd be curious to find out about real-life use-cases.
