Apache Groovy

Apache Groovy is a multi-faceted language for the JVM. It aims to provide a Java-like feel and syntax, but with added productivity features. It supports OO and functional paradigms, and offers both static and dynamic natures for strong yet flexible typing. It supports the creation of powerful scripts and elegant Domain-Specific Languages. It offers bidirectional interoperability with Java classes and libraries, and supports language extensions through in-language macros, AST transformations and meta-programming.
