I have the same doubt. In any case, in the DSL for one of my adventure 
engines I used this form:

  look.clock = Msg('M_007')

  act.clock = Msg('M_005')

  use.hammer.clock = function()
      Say('M_005')
      MoveTo(secret_door)
  end

  use.any.clock = Msg('M_008')

where (self-built) tables such as "use.hammer.clock" describe a possible 
player's action and the right side describes the desired effect, either 
as a user-defined function or as a pre-built command.

(the DSL I designed for a game-book compiler was more interesting, but 
it also had a preprocessing stage so it was not entirely pure Lua)
