How about making offset a standard integer, and change the signature to return a 
tuple when it is used:

   item = unpack(format, rec) # Full unpacking
   offset = 0
   item, offset = unpack(format, rec, offset) # Partial unpacking

The second item in the returned tuple being the offset of the first byte after 
the end of the unpacked item.

Cheers,
Nick.
