This one is interesting. Because @tport is shown to the object,
and not the enactor, we use did_it(thing,thing,....)

That means %# gets set to the thing, which is really calling
the message on itself.

We have traditionally handled situations like this by passing
in the extra stuff as %0 (as per GIVE, RECEIVE). We can do that.

Or we can munge real_did_it to accept another dbref that, if valid,
is passed to process_expression as the enactor.

What do you think, folks?
