I have never, ever understood the need to obfuscate code in production. Do people really think it's a security measure? I've heard that touted, but never bought into it.
This may be off topic, but my chaotic brain sees it as relevant, so here goes: There has been some discussion of late as to first, second, and third rate programmers. My take on this is that we should be striving to become first rate communicators and that first rate programming is simply a means to that end. It's not just that we need to be smart about the code we produce. We ultimately need to be smart about how we use that code to get a message across, be it to the end user or the people who must live with our coding decisions, present and future. As FoxtrotUniform points out, the person you help just might be YOU. Obfuscation is a step in the wrong direction, IMHO. Fine as a game or an exercise, but definitely, definitely not for production environs. Consider this a humble third and ++'s to the author. <flame suit on>
