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

val of_map_keys : (Elt.t, _, Elt.comparator_witness) Base.Map.t -> t

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

This function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.
