The ListSetFn functor

Synopsis

functor ListSetFn (ORD_KEY) : ORD_SET

The ListSetFn functor implements applicative sets on an ordered type. It uses a sorted list representation.

Discussion

Note that adding an element to a set that already contains such an element (in the sense that both elements are considered equal by the comparison function) causes the current element to be replaced by the new one.
