Quoting Chuckk Hubbard badmuthahubbard@gmail.com:
I don't see why one would use 'a'. Does anyone ever send floats, lists, and symbols to the same trigger? I mean, the receiving object is just as likely to have a problem with it as the trigger object itself.
i do. there are objects that accept symbols, floats, lists and all kind of other stuff. there are even objecs that output different messages.
