Oh god. It's Perl. And no need to drag it through the mud here. It's pretty much the only language that gets Unicode right. It has nothing in common with the abject misery that is PHP. Perl came out in '87. Erlang came out in '86. I don't know what you're high on, other than trends and trendwhores.

Clojure isn't new. Not to take a dig at Rich Hickey, but everything he is doing with immutable objects was done more than a decade ago by the likes of Henry Baker (http://home.pipeline.com/~hbaker1/home.html). Of course, everything that has ever been tried at all has been tried in some variant of Lisp/Scheme at one point in time.
