+
+    TypedDict creates a dictionary type that expects all of its
+    instances to have a certain set of keys, with each key
+    associated with a value of a consistent type. This expectation
+    is not checked at runtime but is only enforced by typecheckers.
+    Usage::
+
+        Point2D = TypedDict('Point2D', {'x': int, 'y': int, 'label': str})
+        a: Point2D = {'x': 1, 'y': 2, 'label': 'good'}  # OK
+        b: Point2D = {'z': 3, 'label': 'bad'}           # Fails type check
+        assert Point2D(x=1, y=2, label='first') == dict(x=1, y=2, label='first')
+
+    The type info could be accessed via Point2D.__annotations__. TypedDict
+    supports two additional equivalent forms::
+
+        Point2D = TypedDict('Point2D', x=int, y=int, label=str)
+
+        class Point2D(TypedDict):
+            x: int
+            y: int
+            label: str

+    The latter syntax is only supported in Python 3.6+, while two other
+    syntax forms work for 3.2+
