Can't the pipe operator be easily mimicked in Ruby thanks to its flexibility?

I'm thinking of something like this:

    class Object
      def |>(fn)
        fn.call(self)
      end
    end

which then can be in the following way:

    result = arr
      |> ->(a) { a.uniq }
      |> ->(a) { a.flatten }
      |> ->(a) { a.map(&:tags) }

Or if we just created an alias for then #then method:

    class Object
      alias_method :|>, :then
    end

then it can be used like in this way:

    arr
      |> :uniq.to_proc
      |> :flatten.to_proc
      |> ->(a) { a.map(&:tags) }
