For example, `2.3.1 :001 > s = 'test' => "test" 2.3.1 :002 > a = [SimpleDelegator.new(s), SimpleDelegator.new(s)] => ["test", "test"] 2.3.1 :003 > a[0] == a[1] => true 2.3.1 :004 > a.uniq() => ["test", "test"] 2.3.1 :005 > a[0].hash == a[1].hash => true` Kind of strange behavior, especially reading the documentation. Now maybe, `Array#uniq` should be changed to use #== instead of #eql? -- https://bugs.ruby-lang.org/ Unsubscribe:
