nit: use a tuple of single strings instead of a space-delimited string. This is
my personal preference, so if you really like space-delimited strings better go
for it.

[iannucci, 2016/10/06 22:47:11]

I usually do the space delimited string because namedtuple's implementation is
horrifying and using anything other than space delimited strings is just fooling
yourself. Also it's shorter.
