This looks like an “accumulator” pattern- we associate an injector with the collection that we want to operate on and then the method (rsend) is the operative accumulator:

class Array
  def inject(n)
     each { |value| n = yield(n, value) }
     n
  end
 
  def rsend(baseobj)
    inject(baseobj) { |n, value| n.send(value) }
  end
end

Then we’d use it like so:

[:comments, :first, :commented_at].rsend(:post)
