RE: My latest attempt

[turnstep]

Nice. I would add a final newline in there as well.

[mdillon]

good idea. you could use $/ to get a line ending, maybe turning 'print @a' into 'print @a.$/'.

I'm inclined to think that the current hiding place of the newlines is even more obfuscated then $/. I could easilly add the extra newline without reducing the obfuscation. I'll think about making said revision to the original.

UPDATE:
Okay, I've decided that the proposed update actually makes some sense. I also voted for turnstep and mdillon's posts. So here it is:

$_=' 2|21|32|52|47|45|9l3|51A19a4|46|28|34|54M0y1t5'
.q&!38e14|30|49|57s7|26o43t29|16p10P48r11|50|42|58&;
sub s{while($b=shift){$a[shift]=$b};print@a=>$/}$_.=
q#c27|55|15o12:17u25|37n20H53|33(40)59k56|36m44j13t8
39|18e6f24|41O22b23d31i35#;while#a4|46|28:17u25|37';
(s&(\D?)(\d+?)\|&$1$2$1&){};@_=split/(\d+)/;&s#eval;


Enjoy!
