in reply to a prime bug

Nice. But __END__ should be __DATA__ and __END__ be -- well, at the end.

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'

    I suppose, if you want to be formal about it.
    iirc, __END__ and __DATA__ are equivalent, and that's why the script runs. Please correct me if you know otherwise.

      Running a script - perl script.pl - the tokens make no difference. But if you invoke perl on the command line to read STDIN and paste the script, __END__ makes DATA into STDIN, and you have to type Ctrl-d to close STDIN/DATA. Not a big deal, but that's the difference ;-)

      perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
