limits of actions

1998-01-21 00:36:17
So the action limitations need to be spelled out in the draft, right?

That is, some actions need to prohibit other actions from happening.

obviously necessary:
* Only one reply per message is reasonable.  (You can only reply to one
  place.)
* Only one reject per message.  (You can only reject the message to the
  sender once.)

good ideas:
* reject prohibits forward.  (or forward prohibits reject.)
* reject prohibits keep/fileinto.

possibilities:
* only one forward per message.

In the case where there's a conflict, what happens?  Three possibilities:
* require implementations to reject any script they can't guarantee will
  have problems (this is pretty hard)
* take the first/last action specified, and just get on with life
* run-time error, do a keep, then mail the user explaining what happened
