As stated by Guido (and pointed out in the PEP): Making **kwds ordered is still open, but requires careful design and implementation to avoid slowing down function calls that don't benefit. The PEP has not been updated in a while, though. Python 3.5 has been released, and with it a C implementation of OrderedDict. Eric, are you still interested in this? IIRC that PEP was one of the motivating use cases for implementing OrderedDict in C. Maybe it's time for a second round of discussion on Python-ideas? -Emanuel _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
