TypedDict: _SpecialForm
"""A simple typed namespace. At runtime it is equivalent to a plain dict.

TypedDict creates a dictionary type such that a type checker will expect all
instances to have a certain set of keys, where each key is
associated with a value of a consistent type. This expectation
is not checked at runtime.

Usage::

    class Point2D(TypedDict):
        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 can be accessed via the Point2D.__annotations__ dict, and
the Point2D.__required_keys__ and Point2D.__optional_keys__ frozensets.
TypedDict supports an additional equivalent form::

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

By default, all keys must be present in a TypedDict. It is possible
to override this by specifying totality::

    class Point2D(TypedDict, total=False):
        x: int
        y: int

This means that a Point2D TypedDict can have any of the keys omitted. A type
checker is only expected to support a literal False or True as the value of
the total argument. True is the default, and makes all items defined in the
class body be required.

The Required and NotRequired special forms can also be used to mark
individual keys as being required or not required::

    class Point2D(TypedDict):
        x: int  # the "x" key must always be present (Required is the default)
        y: NotRequired[int]  # the "y" key can be omitted

      Ts = TypeVarTuple('Ts')

    From Python 3.11, this can also be done using the `*` operator:

        Foo[*tuple[int, str]]
        class Bar(Generic[*Ts]): ...

    The operator can also be used along with a `TypedDict` to annotate

      # *year* of type `int`.

    Note that there is only some runtime checking of this operator. Not
    everything the runtime allows may be accepted by static type checkers.

        method.

        - ``eq_default`` indicates whether the ``eq`` parameter is assumed to be
          True or False if it is omitted by the caller.
        - ``order_default`` indicates whether the ``order`` parameter is
          assumed to be True or False if it is omitted by the caller.
        - ``kw_only_default`` indicates whether the ``kw_only`` parameter is
          assumed to be True or False if it is omitted by the caller.
        - ``frozen_default`` indicates whether the ``frozen`` parameter is
          assumed to be True or False if it is omitted by the caller.
        - ``field_specifiers`` specifies a static list of supported classes
          or functions that describe fields, similar to ``dataclasses.field()``.

        At runtime, this decorator records its arguments in the
        ``__dataclass_transform__`` attribute on the decorated object.

    TypeIs: _SpecialForm
    """Special typing form used to annotate the return type of a user-defined
    type narrower function.  ``TypeIs`` only accepts a single type argument.
    At runtime, functions marked this way should return a boolean.

    ``TypeIs`` aims to benefit *type narrowing* -- a technique used by static
    type checkers to determine a more precise type of an expression within a
    program's code flow.  Usually type narrowing is done by analyzing
    conditional code flow and applying the narrowing to a block of code.  The
    conditional expression here is sometimes referred to as a "type guard".

    Sometimes it would be convenient to use a user-defined boolean function
    as a type guard.  Such a function should use ``TypeIs[...]`` as its
    return type to alert static type checkers to this intention.

    Using  ``-> TypeIs`` tells the static type checker that for a given
    function:

    1. The return value is a boolean.
    2. If the return value is ``True``, the type of its argument
    is the intersection of the type inside ``TypeIs`` and the argument's
    previously known type.

    For example::

        def is_awaitable(val: object) -> TypeIs[Awaitable[object]]:
            return hasattr(val, '__await__')

        def f(val: Union[int, Awaitable[int]]) -> int:
            if is_awaitable(val):
                assert_type(val, Awaitable[int])
            else:
                assert_type(val, int)

    ``TypeIs`` also works with type variables.  For more information, see
    PEP 742 (Narrowing types with TypeIs).

        it's called; calling it twice on the same object will return two
        different but equivalent dicts.

        This is a backport of `inspect.get_annotations`, which has been
        in the standard library since Python 3.10. See the standard library
        documentation for more:

            https://docs.python.org/3/library/inspect.html#inspect.get_annotations

        This backport adds the *format* argument introduced by PEP 649. The
        three formats supported are:
        * VALUE: the annotations are returned as-is. This is the default and
          it is compatible with the behavior on previous Python versions.
        * FORWARDREF: return annotations as-is if possible, but replace any
          undefined names with ForwardRef objects. The implementation proposed by
          PEP 649 relies on language changes that cannot be backported; the
          typing-extensions implementation simply returns the same result as VALUE.
        * STRING: return annotations as strings, in a format close to the original
          source. Again, this behavior cannot be replicated directly in a backport.
          As an approximation, typing-extensions retrieves the annotations under
          VALUE semantics and then stringifies them.

        The purpose of this backport is to allow users who would like to use
        FORWARDREF or STRING semantics once PEP 649 is implemented, but who also
        want to support earlier Python versions, to simply write:
