The types of map and filter_map are subtle. The input set, ('a, _) set, reflects the fact that these functions take a set of *any* type, with any comparator, while the output set, ('b, 'cmp) t, reflects that the output set has the particular 'cmp of the creation function. The comparator can come in one of three ways, depending on which set module is used

Set.map -- comparator comes as an argument
Set.Poly.map -- comparator is polymorphic comparison
Foo.Set.map -- comparator is Foo.comparator

Never requires a comparator because it can get one from the input Map.t.
