"Project Lambda is a big win for Java developers. It will enable us to write better code -- shorter, more declarative, easier to understand and maintain. And the cost in terms of additional language complexity is kept to a minimum. If you want to try out the new lambda features, you can download the latest JDK8 binary snapshot from jdk8.java.net/lambda (see the references below). For IDE support, IntelliJ IDEA version 12 has full support for JDK 8."
