Well... say I get an email or usenet message with a perl program in the body:

From: my@email.com
To: your@email.com
Subject: perl program

Hello here is my program
hope you like it,

Joost.


#!/usr/bin/perl -w
use strict;
print "Just another perl hacker\n";
[download]

I can save it as "message.txt". And then

> perl -x message.txt
Just another perl hacker
[download]

It's just another example of perl making easy things easy.
