Hi I have a piece of code, when a no is passed twice it will just print out saying the no is called twice. But unfortunately it's not working as intended. Any thoughts ? Thanks 

{ 
  my $last = 5;
   sub do_stuff {
       my $arg = @_;
         if ( $arg == $last ) {
             print "You called me twice in a row with $arg\n";
         }
     $last = $arg;
    }
}
do_stuff($_) for 0..5;
