    Hmm.. I'm surprised to see it works to reverse a scalar like that. read's 2nd argument is a SCALAR, and reverse's single argument is a LIST. What is it I do not understand?

      From reverse

      reverse LIST
      In list context, returns a list value consisting of the ele-
      ments of LIST in the opposite order.  In scalar context, con-
      catenates the elements of LIST and returns a string value with
      all characters in the opposite order.

        In list context: 
        my @array = reverse( LIST );

        In scalar context: 
        my $value = reverse( LIST );

        Fine. But it does not say how it's supposed to behave when fed a SCALAR instead of a LIST, does it?

        I'm still confused.
