It would be nice if the MenuComponent interface had a method that
was invoked by awt when the menu item was pressed.

Currently, menu processing code is distributed through my program in
three places.
   ... creating the MenuItems
   ... handling the menu events on my Frame
   ... actually doing the work implied by the menu item

This makes it difficult (impossible?) to encapsulate a task as an
object by subtyping MenuItem.

For example, it would be nice to be able to simply go:
    menu.add(new FileOpenMenuItem());

where a FileOpenMenuItem was an object that responded to the menu press
(by the new method being suggested) and could then do whatever was
necessary to open a file (or whatever).
