I don't want to unroll x, y in the function API because the function signature is that it takes a position object. The fact that the position object just happens to be a 2 element tuples as no incidence on that. I want the function API to be that. Why would you ask ? Because it make sense to do it like that when I create a second function which takes 2 posiiton objets. Why should I call the first with that sytnax : f(*pos) and the second with that one : g(pos1, pos2) -- http://mail.python.org/mailman/listinfo/python-list
