      -----------------------------
           #!/usr/bin/perl
           # this just re-implements tail -1
           #
           # usage:
           #   /this/file < /some/text/file.txt
           #

           my $last;

           while( <> ) {
             $last = $_;
           }
           
           print $last;
      -----------------------------

Now, try with the "my $last;" *inside* the while().  That last print
line won't have a clue what $last is.
