Another bit of newslore, this time provoked by Kent Pitman‘s article The Best of Intentions, Equal Rights–and Wrongs–in Lisp, which discusses the fine print of equality and copy operations in Lisp. Pascal Bourguignon has written a beautiful news post at comp.lang.scheme that shows how each of the possible meanings of copy mentioned in Pitman’s article can be implemented in Scheme, complete with nice ASCII-art box diagrams. Recommended reading.
