Using_comparator.Tree
A Tree.t
contains just the tree data structure that a set is based on, without including the comparator. Accordingly, any operation on a Tree.t
must also take as an argument the corresponding comparator.

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 argumentSet.Poly.map
-- comparator is polymorphic comparisonFoo.Set.map
-- comparator is Foo.comparator
