I looks like all you need is for objects to be enumerable, i.e have
instances of Enum. So instead of the above class, can you manage with
these two functions?
get :: Enum e => e -> Int
put :: BitSet -> String
Type classes give you type-based dispatch - *but* they are overkill if
you don't actually need type-base dispatch.
