JAPF

A little quickie. Its novelty is that it doesn't simply unscramble itself to generate its output. I can't guarantee it will run on every system, but I think it should, if you have a complete installation of Perl. It certainly works with ActivePerl.

Bonus points if you guess what the F in the title is for. (No, it's not vulgar.)

Update: ambrus notes that changes in 5.10.0 cause it to print twice.

Congratulations, you have found the Mirror of Erised. It must be a bad feeling to read about this, but I still have to tell that at least three people have found this idea before you (and one of them was me): the previous japhs are Opere Citato Japh, One-liner japh, Just Another JAPH, and a later one is Perl FAQ. However, I think your implementation is the best of all in that it hides the <Reveal this spoiler or all in this thread> (Update: so well in fact, that I might not even have noticed anything if it wasn't for Not_a_Number's reply. Pity he didn't use spoiler tags for the F-word.) Also note that your japh has a good idea that's worth mentioning in a reply. Most japhs don't have any idea, and just put the overused ideas (like s with strange delimiters, punctation vars) to a visually new form. Some of my japhs are prone to that too.	[reply]

Shucks, instead of each of us re-inventing the wheel, why isn't there a module for this? Oh, wait, there is. `;-)` Caution: Contents may have been coded under pressure.	[reply]

Why? Isn't <Reveal this spoiler or all spoilers in this node or all in this thread> enough? It saves you the reinventing. It's not exactly a module, but <Reveal this spoiler>	[reply]

Bonus points if you guess what the F in the title is for. faq? Update: Forgot to say that I liked it very much. Roy Johnson++. BTW, it seems to have become even more obfuscated since I first looked at it...	[reply]
