def get_args(tp, evaluate=None):
    """Get type arguments with all substitutions performed. For unions,
    basic simplifications used by Union constructor are performed.
    On versions prior to 3.7 if `evaluate` is False (default),
    report result as nested tuple, this matches
    the internal representation of types. If `evaluate` is True
    (or if Python version is 3.7 or greater), then all
    type parameters are applied (this could be time and memory expensive).
    Examples::

        get_args(int) == ()
        get_args(Union[int, Union[T, int], str][int]) == (int, str)
        get_args(Union[int, Tuple[T, int]][str]) == (int, (Tuple, str, int))
