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:
