可以使用以下命令从Ruby对象访问单例类:

some_object.singleton_class

是否可以执行反向操作:在单例类中访问原始对象？

class << some_object
  # how to reference some_object without actually typing some_object?
end

我想干这个方法:

class Example
  PARENTS = []
  class << PARENTS
    FATHER = :father
    MOTHER = :mother
    PARENTS.push(FATHER, MOTHER)
  end
end

并尝试PARENTS用更通用的东西替换类内部.
