Closure JAPH

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 -084 065:13 0001 000005 -0012 -00003 000013 -82 00048 21:13:-6.00:-76:72 -007.:02:00008.00 :::-6.00:::013 -70:3::-70:.64 /];$p=0x4a ;;$h=0; $j->()->()->()->()->()->()->()->()->()->()->()->()->()->()->()->()->() +->()->()->()->()->()->()->()->();

[Corion]: ambrus: Yeah, at least that's what I think I'll start with. A timer and potentially the dummy IO function that never is ready
[ambrus]: That only lets you invoke the main loop from Prima->run;, not from AnyEvent->condvar- >recv; but that shouldn't matter
[Corion]: ambrus: Details ;)
[ambrus]: Like <c>{ package AnyEvent::Impl:: Prima; use Prima; sub io{ my($s,%r)=@_; Prima::File->new( file=>$r{fh},mask =>("w"eq$r{poll}? fe::Write():fe:: Read())|fe:: Exception,onRead =>$r{cb},onWrite =>$r{cb}, onException=>$r{cb }) } sub timer { ... } push @AnyEvent::REGI
[ambrus]: argh, too long, let me try on scratchpad
[Corion]: . o O ( I seem to have improved my skills of getting other people to write code for me )
