Under 1.9.3, when Enumerator.new was called with arguments and block, it return Enumerator object.
But under trunk, it makes TypeError.

 
 $ ruby -v -e "p Enumerator.new([1,2,3]){|y|y.yield 4}"
 ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.4.2]
 #<Enumerator: [1, 2, 3]:each>
 
 $ ./ruby -v -e "p Enumerator.new([1,2,3]){|y|y.yield 4}"
 ruby 2.0.0dev (2012-11-07 trunk 37528) [x86_64-darwin12.2.0]
 -e:1:in `initialize': can't convert Array into Integer (TypeError)
 	from -e:1:in `new'
 	from -e:1:in `<main>'
