   single one corresponding to `@CompileStatic(TypeCheckingMode.SKIP)`.

positive.code: 
  ===== Anonymous inner class
  
  The last example of inner class can be simplified with an anonymous inner class. The same functionality can be achieved with the following code.
  
  [source,groovy]
  ----
  
negative.code:  * They provide a good organization, by grouping classes that are used by only one class.
   * They lead to more maintainable codes, since inner classes are near the classes that use them.
  
  It is common for an inner class to be an implementation of some interface whose method(s) are needed by the outer class.
  The code below illustrates this typical usage pattern, here being used with threads.
  
  [source,groovy]
  ----
  include::../test/ClassTest.groovy[tags=inner_class2,indent=0]
  ----
  
  Note that the class `Inner2` is defined only to provide an implementation of the method `run` to class `Outer2`.
  Anonymous inner classes help to eliminate verbosity in this case.
  That topic is covered shortly.
  
  Groovy 3+ also supports Java syntax for non-static inner class instantiation, for example:
  
  [source,groovy]
