In 1.8, NODE_SCOPE creates a new scope.

Using ParseTree's parse_tree_show:

class Example
   def example
     1 + 1
   end
end

Has the AST:

[[:class,
   :Example,
   :Object,
   [:defn,
    :example,
    [:scope, [:block, [:args], [:call, [:lit, 1], :+, [:array, [:lit,  
1]]]]]]]]

But I don't recall if a NODE_SCOPE can be created outside of a def.   
(At least, I haven't seen any show up.)  But 1.8 is likely to be  
totally unlike YARV in this respect.
