I have not any use case now. Simply when I have a variadic function,
then I would to allow call it with named notation. Some like

create or replace foo (a int, variadic b int[]) ...

SELECT foo(10 as int, variadic array[10,20] as b)

when I though about control, I found so syntax with mandatory VARIADIC
is difficult implementable. So probably the most feasible solution for
this moment is to discard a variadic functions from set of functions
that are callable with named notation. So I thing we are in tune, and
I am going to update patch.
