Here's a quote from an alleged Facebook employee on Reddit regarding this matter.<p><i>This entire thread needs to go fall in a well and die. If they had just called it a compiler, you nerds would be arguing about the same thing and saying it was a source code transformer. They just called it that because it translates PHP to C++, and to most people who don't have Asperger's that's not the same as compiling.<p>How do I know this? I sit 20 feet from the guys who wrote it.</i><p><a href="http://www.reddit.com/r/programming/comments/ax7k4/facebooks_hiphop_for_php_programmatically/c0jvpya" rel="nofollow">http://www.reddit.com/r/programming/comments/ax7k4/facebooks...</a>
