A bit of fun with pack/unpack

My first, humble attempt at writing (intentionally) obfuscated code:

use strict; use warnings; @==map{unpack('B24',pack('V',$_))}(12580855,16776063,103792,10764419,8 +561235,856483,1974885); foreach$"($[..23){$:=$[;foreach$\($[..6){$:.=substr($=[$\],$",!$[)}pri +nt(pack('B8',$:))}print$/;

    You can shave off a few characters by not using parens, and the blockless form of map:

    use strict; use warnings; @==map unpack('B24',pack'V',$_),12580855,16776063,103792,10764419,8561 +235,856483,1974885; for$"($[..23){$:=$[;for$\($[..6){$:.=substr $=[$\],$",!$[}print pack'B +8',$:}print$/;

      That's so much better, thanks for the tip :-D

    Not too bad. I would suggest reading documentation on functions and finding the little know/used parts of those functions and also thinks about what weird things you can do with them.
