@checksignature
def function(a: str, b: int, c, *args: int, **kwargs: int)::

function('one', 2, 3.0, 1, 2, 3, **{'four': 4})   #=> functions as usual--no problem.
function('one', 2, 3.0, 1, 2, 3, **{'four': 4.0}) #=> raises a TypeError
function('one', 2, 'x', 1, 2, 3, **{'four': 4})   #=> raises a TypeError
