Support declaring TypedDict type with class-based syntax (for Python 3.6+) #2740
Description
- Support basic declaration:
class Point2D(TypedDict):
x: int
y: int
- Support class-based inheritance as syntactic sugar for copying fields
class Point3D(Point2D):
z: int
There is already support for the above syntaxes at runtime but the typechecker doesn't reconcognize it yet.

@davidfstr I wanted to work on this soon. Do you prefer to do it yourself?
davidfstr commentedon Jan 25, 2017
@ilevkivskyi Go for it. Help is definitely welcome, as my coding time outside work is highly constrained.
In case it's of interest the next item I'm working on is #2492 and #2739 (together).

I see
error: TypedDict class syntax is only supported in Python 3.6when trying to inherit in the class fashion above. wondering if there is another approach
