+The reason for the different naming of the C<builder> is that the C<builder>
+method is a private method while the C<clearer> and C<predicate> methods
+are public methods.
 
 NOTE: This means your class should provide a method whose name matches the value
-of the builder part, in this case _build_foo or build_foo.
