Whoa whoa whoa. I wasn't suggesting a namedtuple literal. Let's not
bring down the wrath of the gods.

(Also, it's come up before
(https://mail.python.org/pipermail/python-ideas/2014-April/027434.html)
and I was part of the discussion
(https://mail.python.org/pipermail/python-ideas/2014-April/027602.html).
So it's not my idea.)

(And it shouldn't be namedtuple, exactly, since namedtuple is a
metaclass which generates classes with names. Attrtuple? For
performance, it would map [keylist] => attrtuple[keylist]. Earlier
