hi there,

I'm tryng to get my concepts right here.. can you please help in defining a 
funtion like

makeSet :: (a->Bool)->Set a

I understand that we need a new type Set like
data Set a = Set (a->Bool) what puzzles me is how to apply the funtion
to all elements belonging to type a. [a] refers to a list of any type, 
similarly how to access all elements of type a.

All help will be greatly appreciated..
