What is Groovy++?

Groovy++ is a statically typed extension to the Groovy programming language. Groovy++ provides high performance and compile time type checking for compiled code.

Beyond all the goodies of standard Groovy, this project 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)
• standard library of utilities for functional programming, concurrency and distributed computing (early prototype stage)

Hello, World!

Here is simple "Hello, World" application with Groovy++. The call to the String.toLowerCase method is statically resolved by the compiler

@Typed package mypackage

["Hello, ", "World!"].each {
   print it.toLowerCase ()
}
println ()
