This is why I'd like 'def' to return the UnboundMethod object. This 
would let us write

     externally_typed(nil, String, String) def set_name(first, last)
        @first = first
        @last = last
        nil
     end

     externally_typed(String) def get_name
       @first + " " + @last
     end

(where String might also be "xsd:string" or whatever)

It would also be nice if method reflection gave us the names of the 
parameters, but that's not strictly necessary to get this scheme off the 
ground.
