Module#includeandModule#prependnow affect classes and modules that have already included or prepended the receiver, mirroring the behavior if the arguments were included in the receiver before the other modules and classes included or prepended the receiver. [Feature #9573]Exampleclass C; end module M1; end module M2; end C.include M1 M1.include M2 p C.ancestors #=> [C, M1, M2, Object, Kernel, BasicObject]
