Yesterday I sat down and started hammering out my formal parser, and
came to that realization as well.  My parser makes sure that each
grammatical construct
in the command can be resolved, and then passes a command object
(consisting of
each resolved object, indirect object, verb, etc.) to whichever
should handle the command.  This way every verb-handler is assured of
valid data--it need only check to see if the objects are in the correct
places for it to complete its action.  I leave that up to the verbs,
I intend to allow certain leeway if you're an admin character (i.e.
admin's can type things like "get Bubba's bag" and have it do just that
matter where you are in the world, while a player will only be able to
Bubba's bag" if he's in the same room as the bag, it is a top-level
item, etc.).
