I know that for historical purposes,OrderedDict.__repr__ displays key-value pairs in the format of[(key, value), ...], since the{key: value, ...} representation did not respect the ordering thatOrderedDict needs. However, this was only in the past and it has become a while since dictionaries have become ordered, so I was wondering if changing theOrderedDict.__repr__ to displayOrderedDict({key: value, ...}) instead would be fine. The main rationale is that this is syntactically cleaner to read, often I have found the other representation to be a lot more clunky. Other than potentially breaking things like doc-tests, I don't see much issue with this. The only potential ambiguity that I see is the fact that one might not be immediately sure that the dictionary is ordered, but the fact that it is wrapped byOrderedDict(...) would probably dispel any doubts.
