Hello, Ruby dev team.

I tried Ruby 2.0 trunk, and found Enumerator::Lazy a bit weird.

> [1, 2, 3].cycle.lazy.take 5
# => #<Enumerator::Lazy: #<Enumerator::Lazy: #<Enumerator: [1, 2, 3]:cycle>>:take(5)> 

> [1, 2, 3].cycle.lazy.take_while {|i| i < 3 }.lazy.take(2)
# => #<Enumerator::Lazy: #<Enumerator::Lazy: #<Enumerator::Lazy: #<Enumerator: [1, 2, 3]:cycle>>:take_while>:take(2)>

> [1, 2, 3].cycle.lazy.take_while {|i| i < 3 }.lazy.take(2).lazy.take(3).lazy
# => #<Enumerator::Lazy: #<Enumerator::Lazy: #<Enumerator::Lazy: #<Enumerator::Lazy: #<Enumerator: [1, 2, 3]:cycle>>:take_while>:take(2)>:take(3)> 

Is this type of infinite nesting desirable?

Thank you,

I understand Enumerator::Lazy's behavior via

Sorry for making a noise...
