Maybe we should define exactly "ordered" somewhere the language reference: https://docs.python.org/dev/reference/index.html I expect: * a mapping: mapping ABC, https://docs.python.org/dev/library/collections.abc.html#collections-abstract-base-classes * ordered by definition order * no more I mean: OrderedDict has extra methods, reversed() and movetoend(). Users should not rely on them.
Adding "ordered mapping" to the glossary and linking to the term from the language spec should cover that. Maybe Eric can add it since he made the spec updates earlier? -------------- next part -------------- An HTML attachment was scrubbed...
