CPython max() is declared METH_VARARGS | METH_KEYWORDS, so it's called
with both an args tuple and a kwds dict. Using a keyword argument
other than "key" will raise a TypeError. As far as unpacking the args
tuple, if it's length 1 then the first argument is assumed to be an
iterable. Otherwise the args tuple itself is used as the iterable.
