I have a byte string (Python 2.x string), e.g.:

I wish to convert it to a long integer, treating it as base-256.
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.
One possibility is that Steven wants to apply bitlevel and/or arithmetic
operations for e.g. some custom cryptographic thing. The string that he uses as
example is not completely unlike a message digest.
Another possibility is custom serialization/deserialization.
But it would be nice to know what it's actually about...
