The first "cons cell" C extension for Python I know about was written in 1994: http://www.python.org/search/hypermail/python-1994q2/0110.html There have been others, but the audience for them appears so small that none catch on. Like Phillip Eby, I use 2-tuples for this when I feel the need (usually during a backtracking graph search, to keep track of paths back to the root in a space-efficient way), and am happy with that. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
