I understand why you can't have two stars in a function definition; But
why can't you have two (or more) stars in a function call?
Would there be any advantage over `f(*(my_list + my_other_list))`?
That fails if my_list and my_other_list are different types, whereas
the *args syntax happily accepts any iterable object.
But I think it's still a rare enough use case to require
f(*(tuple(my_list) + tuple(my_other_list)))
when you need it, although the concatenation would likely get split up and
moved into an explicit variable anyway.
