namedtuple is great and clever, but it’s also a bit clunky. It has a weird signature and requires a made up type name. It’s also rather unPythonic if you want to support default arguments when creating namedtuple instances. Maybe as you say, a lot of the typical use cases for namedtuples could be addressed by a better builtin, but I fear we’ll end up down the bikeshedding hole for that.

My aenum library [1] has a metaclass-based NamedTuple that allows for default arguments as well as other goodies (which would probably not make it to the stdlib since they are mostly fluff).
