Bug Report

In the typing docs for TypedDict there is an example of defining a TypedDict using keywords mapped to types

Point2D = TypedDict('Point2D', x=int, y=int, label=str)

When running mypy on this exact example, I get the following error:

type_test.py:4: error: Too many arguments for TypedDict()

If using the alternative definition with a positional dictionary, no error.

Point2D = TypedDict('Point2D', {'x': int, 'y': int, 'label': str})

To Reproduce
