My take on Larry Wall's classic work of art; the Black Perl poem. Parses and runs with perl v5.20.

black_perl-520.pl

#!/usr/bin/env perl
no warnings;

BEFOREHAND: close door, each window & exit; wait until time.
  open spellbook, study, read (scan, $elect, tell us);
write it, print the hex while each watches,
  reverse its, length, write, again;
kill spiders, pop them, chop, split, kill them.
  unlink arms, shift, wait & listen (listening, wait),
  sort the flock (then, warn "the goats" & kill "the sheep");
kill them, dump qualms, shift moralities,
  values aside, each one;
die sheep? die to : reverse { the => system
  ( you accept (reject, respect) ) };
next step,
  kill `the next sacrifice`, each sacrifice,
  wait, redo ritual until "all the spirits are pleased";
do { it => "as they say" }.
  do { it => (*everyone***must***participate***in***forbidden**s*e*x*) }.
  return last victim; package body;
exit crypt (time, times & "half a time") & close it,
  select (quickly) & warn your (next victim);
AFTERWARDS: tell nobody.
  wait, wait until time;
wait until next year, next decade;
sleep, sleep, die yourself,
  die @last
