Currently reading an article, "First Class Relationships in an Object- oriented Language", by Gavin Bierman and Alisdair Wren: http://homepages.inf.ed.ac.uk/wadler/fool/program/final/4/4_Paper.pdf
Found in the "Lambda the Ultimate" blog: http://lambda-the-ultimate.org/node/2013 Maybe it can be done in Python too, with a metaclass "Relationship". The relation can probably be added dynamically to an object/class. Some typecheek can be added too, if necessary. Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
