ruby1.9

According to this rubyquiz, external iterators used to be slow, but are now faster. Is this an improvement only available in YARV (the C-based implementation of ruby 1.9), or is this also available in the C-based implementation of ruby 1.8.7?

Also, does enum_for rely on external iterators?
