When I go back and re-read your message things are very clear. I am not
sure what I saw when I first read it to think what I did. Comment retracted
as not-helpful. Sorry.

Not setting @_ could be a problem for tail-end recursion using goto &foo;

I love the signatures. I also love controlled and sane use of goto &sub. I
would not be happy if signatures made goto &sub harder.

When you say @_ is unset, do you mean it is empty, but still a unique array
for each function? if @_ was arguments to a function higher up the stack I
could see that as a total disaster (but I am hoping nobody proposed that).
If by empty you mean @_ will be an empty array for functions with
signatures, that would not bother me so much.
Nowhere in my email do I use the word 'unset'. I proposed 4 options,
A1..A4, each of which causes @_ to behave in a particular way.
Which of those options are unclear to you?
