As I said before. Let us get rid of the distinction.
Here is Randal and Graham arguing about a 'fundamental' issue. I don't
think this is fundamental to 'What is Perl'. This is a great question
to stump someone on an interview.
Ignoring this "push a list/comma seperated list context through a
subroutine half way across the world".
Why can't we have an anonymous array on the 'stack' (If the stack will still
be there after -internals have a go at things?
