Getopt eats up the values in @ARGV so it is alway empty

Just to be nitpicky -- not quite. Getopt eats the options in @ARGV. Anything else will remain. Consider the following: 

#!/usr/bin/perl

use Getopt::Long;

GetOptions(
    "i" => \$options{i},
    "o=s" => \$options{o},
    "p=s" => \$options{p},
    "h" => \$options{h}
);

foreach $arg (@ARGV) {
    print "$arg is still in ARGV\n";
}

foreach $opt (keys %options) {
    print "$opt is $options{$opt}\n" if $options{$opt};
}

and note the output: 
nkuvu$ perl try.pl --i h --o=foo
h is still in ARGV
o is foo
i is 1

I have used this to check some command line inputs. Specifically, for most of my scripts anything specified on the command line should be an option. Anything after that is an error. So I'd use it sort of like: 

GetOptions(
  #whatever
);

die "Gah! (with appropriate error message here)\n" if (@ARGV);
