  AbstractExtensionMethodCache
  AbstractTypeCheckingExtension
  Custom type checking extensions may extend this method in order to benefit from a lot of support methods.
  DefaultTypeCheckingExtension
  The default type checking handler is used by the standard type checker and doesn't handle any of the type checking errors by default.
  EnumTypeCheckingExtension
  A type checking extension that will take care of handling errors which are specific to enums.
  ExtensionMethodCache
  This class is used to make extension methods lookup faster.
  ExtensionMethodNode
  Represents method nodes which are used by the static type checker to virtually add methods coming from `DGM-like` methods.
  GroovyTypeCheckingExtensionSupport
  Base class for type checking extensions written in Groovy.
