With my Modula background, where a machine-oriented SET type is available,
I consider using integers as bit sets (as in Data.Bits) as a hack.  
Assuming that integers are stored by binary numbers might be true for all
todays computer systems, but I wouldn't count on that.
 According to its interface, Data.IntSet might be an option for you.
