+SUMMARY="Backported and experimental type hints for Python"
+DESCRIPTION="The 'typing_extensions' module serves two related purposes:
+
+- Enable use of new type system features on older Python versions. For example,
+  'typing.TypeGuard' is new in Python 3.10, but 'typing_extensions' allows
+  users on previous Python versions to use it too.
+- Enable experimentation with new type system PEPs before they are accepted and
+  added to the 'typing' module.
+
+'typing_extensions' is treated specially by static type checkers such as mypy and pyright.
+Objects defined in typing_extensions are treated the same way as equivalent forms in 'typing'.
+
+'typing_extensions' uses Semantic Versioning. The major version will be incremented only for
+backwards-incompatible changes. Therefore, it's safe to depend on typing_extensions like this:
+'typing_extensions >=x.y, <(x+1)', where 'x.y' is the first version that includes all features
+you need."
