I want to take a list of inputs and simply print out each element in the order in which they occur.

This sounds simple, but my code doesn't work (prints a blank line). 

#!/usr/bin/perl -w
use strict;

my @inputs = ();
my @values = ();

@inputs = @ARGV;

foreach my $elemnt (@inputs)
    {
    if (grep {$_ ne $elemnt} @values)
        { push @values, $elemnt; }
    }

print "@values\n";

Suspecting an initialization problem, I tried an alternate version where I pre-seeded one element in @values, but that printed every input value (not removing duplicates).
