I've actually thought about this a lot! 1. no more keyword parameters 2. every message has exactly one argument, which may be a tuple. 3. "obj.msg" becomes short hand for "obj msg ()" 4. if a message expects 2 element tuple and you give it a one element one.. it returns a closure that expects the rest of the arguments. ie "add1 = 1.+"
