nesting annoyances

This is sadly not as obfuscated as i would like. It is an attempt at obfuscation wherein the engine is not easily understood, in hopes that that will provide a nice groundwork for a good obfu. I just hope the engine is as hard to figure out for others as it was for me :-/

Please tell me what you think,

sub{$0[1]=[reverse+1..$_[0]];{sleep sub{system('clear');print$",join$" +,(map{ $==$_;map($0[$_][$=]||'|',1..3),$/}reverse+0..-1+pop)}->($_[0]);@1[1,3 +,2]=([ 2,3],[1,2],[1,3]);@{$0[3]}==$_[0]||sub{join('',$_[1]?$0[1][$#{$0[1]}]= +=1?$_[ 3]?($_[3],3):$_[2]?($_[2],2):($_[1],1):($_[1],1):$_[3]?$0[3][$#{$0[3]} +]==1?$ _[1]?($_[1],1):$_[2]?($_[2],2):($_[3],3):($_[3],3):$_[2]?$0[2][$#{$0[2 +]}]==1 ?$_[1]?($_[1],1):$_[3]?($_[3],3):($_[2],2):($_[2],2):$|)=~/(.)(.)/;pus +h@{$0[ $1]},pop@{$0[$2]}}->(0,sub{($0[1][$#{$0[1]}]?!$0[$1[1][@{$0[1]}%2]][$# +{$0[$1 [1][@{$0[1]}%2]]}]?$1[1][@{$0[1]}%2]:$0[1][$#{$0[1]}]<$0[$1[1][@{$0[1] +}%2]][ $#{$0[$1[1][@{$0[1]}%2]]}]?$1[1][@{$0[1]}%2]:$%:$,,$0[3][$#{$0[3]}]?!$ +0[$1[3 ][@{$0[3]}%2]][$#{$0[$1[3][@{$0[3]}%2]]}]?$1[3][@{$0[3]}%2]:$0[3][$#{$ +0[3]}] <$0[$1[3][@{$0[3]}%2]][$#{$0[$1[3][@{$0[3]}%2]]}]?$1[3][@{$0[3]}%2]:$, +:$-,$0 [2][$#{$0[2]}]?!$0[$1[2][@{$0[2]}%2]][$#{$0[$1[2][@{$0[2]}%2]]}]?$1[2] +[@{$0[ 2]}%2]:$0[2][$#{$0[2]}]<$0[$1[2][@{$0[2]}%2]][$#{$0[$1[2][@{$0[2]}%2]] +}]?$1[ 2][@{$0[2]}%2]:$-:$!)[($0,0..2)[1,3,2]]}->($@,@0[1,3,2]))&&redo}}->(po +p||3);

    Well, the code crashes MacPerl. What's it supposed to be doing?
      it solves the towers of hanoi for any positive number of disks...

[Discipulus]: hello crew! marto thanks for the message: but I how can I help? i'm testing cpan Padre atm problem with Client::Debug
[choroba]: I don't happen to have 5.10.0 nor 5.8.5 handy...
[Corion]: Hmm - I would say the 5.8.5 is a broken installation / corrupt tarball download, and the 5.10.0 is really weird, and maybe a bug in that version of Perl
[Corion]: I don't see how my $result = eval q{'abc' =~ ?b?}; could create a "Modification of read-only value" error
[marto]: Discipulus the issue that should be adressed is that the page needs to be updated to reflect modern perl on Windows
[Discipulus]: but is really necessary to support these ancient versions? from 5.14 onward is not enough?
[Discipulus]: yes marto I understood
[Corion]: Discipulus: I'm slowly migrating my code to require 5.8.x ;) Most of my code works on 5.6, but Filter::signatures requires 5.10 I think

    Should cpanminus be part of the standard Perl release?
