    This decorator makes it easy to support Python 3 style keyword-only
    parameters. For example, in Python 3 it is possible to write::

        def fn(pos1, *, kwonly1=None, kwonly2=None):
            ...

    All named parameters after ``*`` must be a keyword::

        fn(10, 'kw1', 'kw2')  # Raises exception.
        fn(10, kwonly1='kw1')  # Ok.

    Example
    ^^^^^^^

    To define a function like above, do::

        @positional(1)
        def fn(pos1, kwonly1=None, kwonly2=None):
            ...

    If no default value is provided to a keyword argument, it becomes a
    required keyword argument::

        @positional(0)
        def fn(required_kw):
            ...

    This must be called with the keyword parameter::

        fn()  # Raises exception.
        fn(10)  # Raises exception.
        fn(required_kw=10)  # Ok.

    When defining instance or class methods always remember to account for
    ``self`` and ``cls``::

        class MyClass(object):

            @positional(2)
            def my_method(self, pos1, kwonly1=None):
                ...

            @classmethod
            @positional(2)
            def my_method(cls, pos1, kwonly1=None):
                ...

    The positional decorator behavior is controlled by
    ``_helpers.positional_parameters_enforcement``, which may be set to
    ``POSITIONAL_EXCEPTION``, ``POSITIONAL_WARNING`` or
    ``POSITIONAL_IGNORE`` to raise an exception, log a warning, or do
    nothing, respectively, if a declaration is violated.

    Args:
        max_positional_arguments: Maximum number of positional arguments. All
                                  parameters after this index must be
                                  keyword only.

    Returns:
        A decorator that prevents using arguments after max_positional_args
        from being used as positional parameters.

    Raises:
        TypeError: if a keyword-only argument is provided as a positional
                   parameter, but only if
                   _helpers.positional_parameters_enforcement is set to
                   POSITIONAL_EXCEPTION.

    If a given key from ``params`` is repeated in the ``uri``, then
    the URI will be considered invalid and an error will occur.

    If the URI is valid, then each value from ``params`` will
    replace the corresponding value in the query parameters (if
    it exists).

    Args:
        uri: string, A valid URI, with potential existing query parameters.
        params: dict, A dictionary of query parameters.

    Returns:
        The same URI but with the new query parameters added.
