  ImmutablePropertyHandler |
  LegacyHashMapPropertyHandler | The `@Immutable` transformation in earlier versions of Groovy tried to be smart in the case of an immutable class with a single HashMap property, the supplied Map constructor tried to be compatible with both expected tuple behavior and expected named-argument behavior by peeking into the supplied map and guessing as to which approach might be applicable.
  PropertyHandler | Used to provide custom property handling when getting, setting or initializing properties.
