According to the docs: https://docs.python.org/3/library/typing.html?#typing.TypedDict, there are two additional equivalent syntax for TypedDict definition.

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

However, the former one is quite confusing since we have the `total` keyword arg for TypedDict. In addition, PEP589(https://www.python.org/dev/peps/pep-0589/#id19) doesn't have this.

I think we could discard the definition syntax using keyword args in the doc.

This is not really just a doc issue then, is it? Maybe we should just deprecate the feature?

I recommend opening an issue here: https://github.com/python/typing/issues/new/choose

Just so that all the discussion related to this issue can be found in one place, here's a summary:

- After opening this ticket, OP opened an issue in the python/typing repository, where the idea of deprecating this syntax received many thumbs-up reactions, and where there were no dissenting voices: https://github.com/python/typing/issues/981
- The initial impetus for this change was this mypy bug report: https://github.com/python/mypy/issues/11555
- Mypy's policy since January 2020 has been that it would be more trouble than it's worth to attempt to support the kwargs-based syntax: https://github.com/python/mypy/issues/2492#issuecomment-579500959

Go ahead and send a or to deprecate it.--
