I've recently been learning clojure, and discovered the clojure REPL for android(https://play.google.com/store/apps/details?id=com.sattvik.clojure_repl&hl=en), which works beautifully for small scripts. Despite this, I haven't seen much adoption amongst the android dev community, despite clojure's powerful yet simple syntax (much more preferable than Java!). Any ideas on why this is the case?
