METHODS

   default_inner
	 ArrayRef[Object] Object->default_inner ()

       Returns an empty "ArrayRef" by default. If you want to setup additional keywords you will have to "around" this method.

   setup_inner_for
	 Object->setup_inner_for(ClassName $class, %args)

       Sets up all handlers in the inner class.

REQUIRED METHODS

   get_identifier

       Required to return the name of the identifier of the current handler.

MODIFIED METHODS

   setup_for

       After the keyword is setup inside itself, this will call "setup_inner_for".
