I thought that was delegation. As in, when one object delegates some or all of it's behaviour to another object: http://code.activestate.com/recipes/52295 > Often used to model a part/whole relationship, hence the name. In mathematics, composition means to make a function by applying a function to the output of another. E.g.: f o g(x) is equivalent to f(g(x)) (Strictly speaking, the "o" in the f o g should be a little circle rather than lowercase "O".) -- Steven -- http://mail.python.org/mailman/listinfo/python-list
