Indeed it lacks that piece of prettiness in the API. And adding a mapping to allow lookups from item to node really means using a orderedset or ordereddict-like structure. Which is why I was proposing to reuse the existing infrastructure. (note that I *cannot* reuse it from my own third-party class, since the necessary bits are all internal) Still you may make the point that ordereddict is not appropriate, andorderedset would be better for this API. Raymond, would you support adding an orderedset to the collections module? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22097> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
