-   Provide basic introspection for generic types and special typing forms.

-   For a typing object of the form ``X[Y, Z, ...]`` these functions return
-   ``X`` and ``(Y, Z, ...)``. If ``X`` is a generic alias for a builtin or
+   Get the unsubscripted version of a type: for a typing object of the form
+   ``X[Y, Z, ...]`` return ``X``. If ``X`` is a generic alias for a builtin or
    :mod:`collections` class, it gets normalized to the original class.
+   If ``X`` is an instance of :class:`ParamSpecArgs` or :class:`ParamSpecKwargs`,
+   return the underlying :class:`ParamSpec`.
+   Return ``None`` for unsupported objects.
+   Examples::

+      assert get_origin(str) is None

    If ``X`` is a union or :class:`Literal` contained in another
    generic type, the order of ``(Y, Z, ...)`` may be different from the order
    of the original arguments ``[Y, Z, ...]`` due to type caching.
