Annotation Type CompileStatic

@Documented
@Retention(value=SOURCE)
@Target(value={METHOD,TYPE,CONSTRUCTOR,FIELD,LOCAL_VARIABLE,PACKAGE})
public @interface CompileStatic

This will let the Groovy compiler use compile time checks in the style of Java then perform static compilation, thus bypassing the Groovy meta object protocol.

When a class is annotated, all methods, properties, files, inner classes, etc. of the annotated class will be type checked. When a method is annotated, static compilation applies only to items (closures and anonymous inner clsses) within the method.

By using TypeCheckingMode.SKIP, static compilation can be skipped on an element within a class or method otherwise marked with CompileStatic. For example a class can be annotated with CompileStatic, and a method within can be marked to skip static checking to use dynamic language features.
