I am adamant against increasing the number of methods of creating
action at a distance. (Look at the planed removal of all the $/, etc
variables. Don't keep adding this type of problem.
So please, If you intend to continue with these proposals, add to the
verbiage, my comments about killing them dead.

That person can't be serious. You can do serioous damage to other
people's code. THey expect not to continue and it does.
This stuff is just asking for trouble.

Yes it is the existance. THere is only _one_ and no good way to control
how to hand off to previous ones. Or context, or ...

If you are doing a try, why are you bothering with $SIG{DIE}.
Any global should only be manipulated by one and only one level. The
main routine. (Even if it is in a subroutine, but) it should be the
sole proviance of the main routine.
All this has been hacked to death way back int he '70s why is this all
being repeated.
