So help us Java!
The Scala (compiler) is slow ?
Clojure is obscure ?
Can we have Ruby & Python on the JVM..? 
Yipee! They exist! 
JRuby 
Jython
Can we use Haskell & Erlang on the JVM...? 
Nooh! Not yet? 
JErlang? 
JHaskell?
Hmmm... 
…. 
(secret 15 seconds of head-scratching pause)
Can we have Lisp languages on the JVM ? 
Yes, please! 
JScheme? 
JRacket? 
Kawa* saves the day! 
*Scheme for the JVM
Real Functional Programming in Java... 
Have you heard of “Lambdas” ?
Is Java slow? 
Is it a misconception?
Is Java dead?
Let’s stop complaining… 
… and become proactive! 
… please come forward! 
… help fix your concerns!
Help us improve the Java / JVM platform...
