It was proposed by Guido to add the following syntax:

Point = typing.NamedTuple('Point', x=int, y=int)
p = Point(x=1, y=2)
p.x

I also like it. Probably, we should also support it for TypedDict.

Seems reasonable, though if NamedTuple already supports keyword arguments, there may be some ambiguity. And this is a Python 3.6+ only feature.

Allow keyword syntax for NamedTuple (#321)

Fixes #302
Example:

    Employee = NamedTuple('Employee', name=str, id=int)

Note that this requires 3.6+ since order of kwargs should be preserved.
