OrderedDict is just a stdlib import away in Py2.7.

Yeah, but... those are ugly. ``m = {}`` is beautiful.

dict == OrderedDict is a cpython implementation detail. Not doing the import is just leaving a footgun for yourself if you ever decide to try PyPy or VOC or similar.

I don't think it's much of a footgun, and I don't think it's limited to CPython.

In Python 3.6, kwargs are ordered. In all versions of Python, kwargs are a dict. Therefore, in any implementation of Python 3.6, dicts are ordered.

The dev team has stopped short of promising that dicts are ordered, but I can't see how one would realistically be harmed by assuming it to be true.

The 3.6 CPython dict item storage algorithm was implemented in PyPy first.
