All
    operations on the proxy are forwarded to the bound object. If no
    object is bound, a ``RuntimeError`` is raised.

    :param local: The context-local object that provides the proxied
        object.
    :param name: Proxy this attribute from the proxied object.
    :param unbound_message: The error message to show if the
        context-local object is unbound.

    Proxy a :class:`~contextvars.ContextVar` to make it easier to
    access. Pass a name to proxy that attribute.

    .. code-block:: python

        _request_var = ContextVar("request")
        request = LocalProxy(_request_var)
        session = LocalProxy(_request_var, "session")

    Proxy an attribute on a :class:`Local` namespace by calling the
    local with the attribute name:

    .. code-block:: python

        data = Local()
        user = data("user")

    Proxy the top item on a :class:`LocalStack` by calling the local.
    Pass a name to proxy that attribute.

    .. code-block::

        app_stack = LocalStack()
        current_app = app_stack()
        g = app_stack("g")

    Pass a function to proxy the return value from that function. This
    was previously used to access attributes of local objects before
    that was supported directly.

    .. code-block:: python

        session = LocalProxy(lambda: request.session)

    ``__repr__`` and ``__class__`` are proxied, so ``repr(x)`` and
    ``isinstance(x, cls)`` will look like the proxied object. Use
    ``issubclass(type(x), LocalProxy)`` to check if an object is a
    proxy.

    .. code-block:: python

        repr(user)  # <User admin>
        isinstance(user, User)  # True
        issubclass(type(user), LocalProxy)  # True

    .. versionchanged:: 2.2.2
        ``__wrapped__`` is set when wrapping an object, not only when
        wrapping a function, to prevent doctest from failing.

    .. versionchanged:: 2.2
        Can proxy a ``ContextVar`` or ``LocalStack`` directly.

    .. versionchanged:: 2.2
        The ``name`` parameter can be used with any proxied object, not
        only ``Local``.

    .. versionchanged:: 2.2
        Added the ``unbound_message`` parameter.

    .. versionchanged:: 2.0
        Updated proxied attributes and methods to reflect the current
        data model.

    .. versionchanged:: 0.6.1
        The class can be instantiated with a callable.
