I would like to stake my own claim to having the first symmetrical JAPH, though.
This code was actually written to demonstrate a little-known operator in Perl. Of course, you're familiar with the "spaceship operator", <=>, so named because it resembles Darth Vader's TIE Fighter in Star Wars. Well, this code uses the super spaceship operator, <<=>>.
That was written in September 1999, and was inspired by something Benjamin Holzmann wrote for The Perl Conference 3.0. There is a more complicated version which doesn't print the reflection, but it's not as aesthetically pleasing, so I prefer this one.1. < 0, push @ tnirp => <<=>> <= print @ hsup ,0 > .1 Just another Perl hacker rekcah lerP rehto +na tsuJ ; print @ tnirp ;
An obscure bug in 5.6.0 forced me to rewrite my script for that version (the bug has been fixed for 5.6.1). Fortunately, the super spaceship operator still works.
.1 . m || <= 0, push @ tnirp => <<=>> <= print @ hsup ,0 => || m . + 1. Just another Perl hacker rekcah lreP rehto +na tsuJ ; print @ tnirp ;
