Closure JAPH

[aitap]

Just thought that a sub returning itself would be a funny thing to write. Well, here it is, a dragon eating its own tail, even if it's not looking like the original one:

#!/usr/bin/perl
use warnings;
use strict;
       my          
      ($j,$        
   a,$p,$h);$      
   j=sub{print(    
  chr($p+=$a->[$   
  h++]));$j};;;$a  
 =[0,        split 
 "[:         \n]+", 
q/43         -002:1

    /];$p=0x4a     
      ;;$h=0;      
$j->()->()->()->()->()->()->()->()->()->()->()->()->()->()->()->()->()
