As Raymond suggests, if order actually matters for a given use case, then use collections.OrderedDict unconditionally without worrying about the behaviour of the default dict implementation. In addition to reducing code churn and improving cross-version and cross-implementation compatibility, doing that also lets the *reader* of the code know that the key iteration order matters.
