Issue #12523 has been updated by Shyouhei Urabe.


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

----------------------------------------
Feature #12523: `Object#values_at`
https://bugs.ruby-lang.org/issues/12523#change-59374

* Author: Tsuyoshi Sawada

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

~~~ruby
class A
  attr_accessors :foo, :bar, :baz

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

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