public @interface CompileStatic
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 classes) 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.
