That reminds me: Is there a generic 'relation' pattern/recipie, such as finding a computer that's "paired" with multiple users, each of who are "paired" with multiple computers, without maintaining dual- associativity? Good: py> user.getcomputers() [ Compie1, Compie2 ] Bad: user._computers.add( compieN ) compieN._users.add( user ) ? -- http://mail.python.org/mailman/listinfo/python-list
