From the groovy++ page http://code.google.com/p/groovypptest/

Groovy++ is statically typed extension of Groovy programming language. Additionally to all goodies of standard Groovy it adds a lot of functionality

  • compile time checking of code
  • as fast as Java performance of compiled code
  • easy mixing of statically and dynamically typed code
  • very powerful type inference
  • tail recursion traits (interfaces with default implementation)
  • extension methods (compile time categories)

It should be mentioned that I believe Groovy++ development has ceased, and static checking is being implemented for Groovy 2 (currently in beta) –  tim_yates May 10 '12 at 8:06

There is a good article on what Groovy++ brings to Groovy here. It includes benchmark results, so you can see the performance difference vs. Groovy and straight Java.

Groovy++ is an extension to the core Groovy 1.x language. You drop the GroovyPP.jar file into the Groovy library directory, add @Typed in front of the package keyword in your code, then run your code just as you would in core Groovy. It infers the types, AND runs faster!
