FWIW I cannot reproduce the bug with Anaconda's Python 3.4.1 (from a
miniconda install):
$ python
Python 3.4.1 |Continuum Analytics, Inc.| (default, Sep 2 2014, 14:00:37)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from collections import namedtuple; vars(namedtuple("T", "a b")(1, 2))
OrderedDict([('a', 1), ('b', 2)])
