This code is largely obsoleted by the development of Quantum::Superpositions, but I can't really justify roping in another module for the project I am doing.

I want to be able to ensure a set of variables will all have values before assigning them to @_

The following code works, but I would like

  1. for such code work under strict refs.
  2. to eliminate the need to have to "my" my variables and then re-list them in @word... anytime that something is repeated in a program, this is a warning flag that either you haven't abstracted things properly or the language does not allow for such abstraction. 
use strict;

sub file_name {
  my ($client_number, $MM, $DD, $S);

  my @word = qw($client_number, $MM, $DD, $S);


  no strict 'refs';


  !defined($_[$_]) and die "$word[$_] not defined"
  or ${$word[$_]} = $_[$_] for (0..$#_);

  "I$client_number$MM$DD$S";
}

file_name 1,2,3,4;
