Just set a size limit, e.g. 30 or 100. It's just a heuristic. I believe somewhere in Python itself I intern string literals if they are reasonably short and fit the pattern of an identifier; I'd worry that the pattern matching would slow down unpickling more than the expected benefit though, so perhaps just a size test would be better. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ 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
