If I understand the goal of "a new namedtuple" correctly, it is not to come up with yet another namedtuple type -- it is 
to make the existing collections.namedtuple a faster experience, and possibly add another way to create such a thing.

This means that the "replacement" namedtuple MUST be backwards compatible with the existing collections.namedtuple, and 
keeping track of type is one of the things it does:

--> from collections import namedtuple
--> Point = namedtuple('Point', 'x y')
--> p1 = Point(3, 7)
--> p1.x
3
--> p1.y
7
--> isinstance(p1, Point)
True
