$ ri instance_methods
------------------------------------------------ Module#instance_methods
     mod.instance_methods(include_super=false)   => array
------------------------------------------------------------------------
     Returns an array containing the names of public instance methods in
     the receiver. For a module, these are the public methods; for a
     class, they are the instance (not singleton) methods. With no
     argument, or with an argument that is +false+, the instance methods
     in _mod_ are returned, otherwise the methods in _mod_ and _mod_'s
     superclasses are returned.

        module A
          def method1()  end
        end
        class B
          def method2()  end
        end
        class C < B
          def method3()  end
        end
     
        A.instance_methods                #=> ["method1"]
        B.instance_methods                #=> ["method2"]
        C.instance_methods                #=> ["method3"]
        C.instance_methods(true).length   #=> 43

        A.instance_methods                #=> ["method1"]
        B.instance_methods                #=> ["method2"]
        C.instance_methods                #=> ["method3"]
        C.instance_methods(true).length   #=> 43
