- reuse and specialization through composition rather than inheritance and overloading
- generic "callback" or "extension point" APIs
- generic "filters" or predicate APIs
many "behavioral" design patterns, such as
Visitor, Strategy, Chain of Responsibility, etc.

package defines three signatures for each functor type--taking zero, one or
two Object arguments.
