A member of actions: what action and opens return. The engine binds it
to the handle and to the screen's state: an action and an edge see the
state, never the data.
Every member takes the generic ScreenHandle as its self: the
binding hands it the assembled handle, and nothing a member answers depends
on the handle's own type (an edge's target is typed by the registry).
