99 bottles of beer

[Jeanne Boyarsky]

Got this link from someone I know: http://99-bottles-of-beer.net/

It's the program 99 bottles of beer on a wall written in different languages. Which language do you think has a cool implementation?

perl, without a doubt:

    ''=~(        '(?{'        .('`'        |'%')        .('['        ^'-')
    .('`'        |'!')        .('`'        |',')        .'"'.        '\\$'
    .'=='        .('['        ^'+')        .('`'        |'/')        .('['

and yes, it does work. I ran it myself.

I did a little research. The original author just wrote a normal perl script, then used a module that obfuscates in a special way to create the pictures.

The original perl was (I believe) this:

use Acme::EyeDrops qw(sightly get_eye_string hjoin_shapes);
my $ninety_nine = <<'BURP';
$==pop||99;--$=;sub
_{($;=($=||No)." bottle"."s"x!!--$=." of beer")." on the wall"}
print+_,", $;!
Take one down, pass it around,
",_,"!

"while++$=
BURP
chop($ninety_nine); $ninety_nine =~ s/\nprint/print/;
print sightly( { Regex         => 1,
                 Compact       => 1,
                 ShapeString   => hjoin_shapes(2,
                                  (get_eye_string('bottle2'))x6),
                  SourceString  => $ninety_nine } );

They site has a whitespace implementation as well, but I didn't think cutting-n-pasting it here would really do any good.
