Check to See if there is Values in Getopt::Long

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Here's a snippet of my code.


#!/usr/bin/perl

use strict;
use Getopt::Long;

GetOptions(
  'a=s' => \my $opt_a,
  'b=s' => \my $opt_b,
  ...
  'z=s' => \my $opt_z,
);
[download]

I have about 26 options and I would want all of the options checked if the user has entered something in the option. I am hoping to do this in a for-loop statement so that it would look cleaner. Something like this.


for my $i (<loop through all the options>) {
  die if ( ! $i );
}

Any suggestions?
