General Development Groovy took a gigantic leap this past April, with the formal release of a new parser aimed at standardizing the language as part of the JSR process. If you weren't paying attention before, now's the time to start. The new syntax is chock full of enhancements to the language designed for a short learning curve and a big payoff. Resident Groovy practitioner Andrew Glover walks through most important changes to Groovy's syntax and shows you a handy feature you won't find in classic Groovy.

JVM does not run dynamic languages very well

Unfortunately for Java folks, natively-compiled dynamic languages such as various Common Lisp implementations (SBCL, Allegro) run much, much faster than JVM-hosted dynamic languages. Also, the JVM lacks many dynamic features that are necessary for full implementations for languages such as Smalltalk. So you won't see "real" dynamic languages on the JVM, just slow scripting toys like Groovy.
