Where oh where is Enumerator? (1.9)

Err… in Ruby 1.9 is Enumerator at the toplevel or in the Enumerable
namespace? Seems to me it was moved to the toplevel at one point, but
now it looks like it’s in Enumerable again… then again I may have
that all backwards. Can someone confirm?

Thanks.

I don’t think it’s back in Enumerable:

guys, shouldn’t that be Enumerator?

Yes.
