Mammouth is a small language that compiles into PHP, inspired by CoffeeScript. It’s compiled to PHP code/files that you can run on your PHP server.
Now I know nothing about this project and just happened to run across it. I’m not a fan of this for php but it did make me think for a minute on why I like CoffeeScript so much.
Granted this is a debate much like tabs vs spaces and there is no winner. Use what you enjoy and always remember, CoffeeScript is for closers. :-)
