Apache Groovy is a object-oriented programming language for the Java platform.
It is both a static and dynamic language with features similar to those of Python, Ruby, Perl,
It can be used as both a programming language and a scripting language for the Java
Platform, is compiled to Java virtual machine (JVM) bytecode, and interoperates
seamlessly with other Java code and libraries.
Groovy uses a curly-bracket syntax similar to Java. Groovy supports closures, multiline
strings, and expressions embedded in strings.
And much of Groovy's power lies in its ASTtransformations, triggered through annotations.
