It might be convenient to have a method that returns multiple attributes of an object.

class A
  attr_accessors :foo, :bar, :baz

  def initialize foo, bar, baz; @foo, @bar, @baz = foo, bar, baz end
end

a = A.new("a", "b", "c")
a.values_at(:baz, :foo) # => ["c", "a"]

I'm not that strongly against it, but wonder if it has actual usage where it is convenient. Do you have any use cases?
