Currently
~~~ ruby
2.5.0-preview1 :001 > arr = (0..100).lazy.uniq{|i| i % 10}
=> #<Enumerator::Lazy: #<Enumerator::Lazy: 0..100>:uniq>
2.5.0-preview1 :002 > arr.to_a
=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
2.5.0-preview1 :003 > arr.to_a
=> []
~~~
Expected
~~~ ruby
2.5.0-preview1 :001 > arr = (0..100).lazy.uniq{|i| i % 10}
=> #<Enumerator::Lazy: #<Enumerator::Lazy: 0..100>:uniq>
2.5.0-preview1 :002 > arr.to_a
=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
2.5.0-preview1 :003 > arr.to_a
=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
~~~
Solution **Enumerator::Lazy#uniq**'s hash should be accessed from yielder memo
