Seems to work only when the colons come in pairs:

#! perl
use strict;
use warnings;

package :::::
{
    sub x
    {
        printf "(%s)\n", __PACKAGE__;
    }
}

package main;

:::::::x();

Produces:

23:01 >perl 405_Obfu.pl
Bareword "::::::" refers to nonexistent package at 405_Obfu.pl line 27
+.
Invalid version format (non-numeric data) at 405_Obfu.pl line 17, near

“Curiouser and curiouser!” cried Alice.

Update: ~~D’oh! (slaps forehead). Of course! :: is a synonym for main, and so is ::main and therefore ::::, likewise ::::::, etc., etc. (See Packages.)~~ This “insight” is wrong — see reply by tobyink, below.

Are you posting in the right place? Check out Where do I post X? to know for sure.
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> <u> <ul>
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).
Want more info? How to link or How to display code and escape characters are good places to start.
