Subject: [ruby-core:56222] [ruby-trunk - Feature #8026] Need Module#prepended_modules


Issue #8026 has been updated by knu (Akinori MUSHA).


What about adding Module#prepend?(other) also, which could be implemented in ruby as follows?

module Module
  def prepend?(other)
    ancestors.find { |mod|
      break false if mod == self
      mod == other
    }
  end
end

We should have a way to get the list of prepended modules of a class or module.

    module Mixin
    end

    module Outer
      prepend Mixin
    end

    Mixin.prepended_modules   #=> []
    Outer.prepended_modules   #=> [Mixin]
