      public static class MetaClassRegistry.MetaClassCreationHandle
      extends Object

  Class used as base for the creation of MetaClass implementations. The Class defaults to MetaClassImpl, if the class loading fails to find a special meta class. The name for such a meta class would be the class name it is created for with the prefix "groovy.runtime.metaclass." By replacing the handle in the registry you can have any control over the creation of what MetaClass is used for a class that you want to have. WARNING: experimental code, likely to change soon
