I thing, so this is possible. But it needs some instructions more. I
would not add some "unnecessary" checks. It needs one cycle over
parameters more (and one array).
* check if last variadic parameter isn't default
* check if last variadic parameter has flag VARIADIC
* check if there are not any other parameter with VARIADIC flag
* some correction in gram.y (procedural code), that allows VARIADIC in
any position when named notation is active.
