I would suggest to write in this way :
my @res = ();
foreach( @ARGV ) {
       open IN, $_ or die "Couldn't open $_: $!\n";
       my @data = <IN>;
       close IN;
        s/\s+//g  for @data;
        @res = ( @res, @data );
You are copying the @res array.  It would be more efficient using push.
        push @res, @data;
