I suppose someone has probably already done this, but
my attempt to find it in SuperSearch failed, so here
goes. I have adapted Black Perl so that it compiles
in Perl 5. It astonished me how few changes were
necessary, and how little they disrupted the mood.
I didn't do this because I like Black Perl (the first
time I read it, I thought, "how perverse"), but more
because, having read that it would not compile in
Perl 5, I felt... challenged. Though in retrospect,
it wasn't much of a challenge. Still, here it is...
# Black Perl, adapted for Perl 5 by Jonadab.
# Adapted from Black Perl, as seen in the Camel,
# 2nd ed., p 553
BEFOREHAND: close door, each window & exit; wait until time;
open spell book; study; read (spell, $scan, select); tell us;
write it, print the hex while each watches,
reverse length, write again;
kill spiders, pop them, chop, split, kill them.
unlink arms, shift, wait and 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 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) and warn next victim;
AFTERWARDS: tell nobody.
wait, wait until time;
wait until next year, next decade;
sleep, sleep, die yourself,
die @last
So now it compiles in Perl 5 (tested with 5.6.1), but
it still doesn't do anything useful. (I think I'm
glad.) I suppose, having taken this step, it is
inevitable that someone will also port it to Perl 6,
in time. As an interesting side note, if you change
$scan back to scan
(as in the original) it compiles but dumps core.
Maybe I should have left it that way.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>

-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
