I think this has changed since 2006. IronPython was originally using the .NET dictionary class and just locking while using it, but it now has a custom dictionary which is thread safe for multiple readers and allows 1 writer. But it doesn't do anything to preserve order of insertions. OTOH changing certain dictionaries in IronPython (such as keyword args) to be ordered would certainly be possible. Personally I just wouldn't want to see it be the default as that seems like unnecessary overhead when the specialized class exists. _______________________________________________ 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
