APL Worth The Effort

Hi, Does anyone here think learni ing APL is worth the effort, I know a few people who revere it as the optiomy of programing but im skeptical. I have a pretty strong background in functional languages (Haskell, CL , Clojure, Scheme, Qi , etc.) and have read my SICP so its concepts shouldnt be too hard for me to learn but I want to know what makes APL 'special' and when it comes down to it useful.
