It's a pretty old idea, that seems to be getting revived in a big way all of a sudden. Perhaps the Java people just rediscovered it? In a Software Engineering class using Ada, the teacher called it "Structural Inclusion", and of course it was an important concept in Ada, because Ada had no inheritance. This was in 1989-1990. -- http://mail.python.org/mailman/listinfo/python-list
