In Rev 28, B.3.1 it states:

 *

   It is a Syntax Error
   ifPropertyNameListofPropertyDefinitionListcontains any duplicate
   entries for|"__proto__"|and at least two of those entries were
   obtained from productions of the
   formPropertyDefinition:PropertyName|:|AssignmentExpression.

I noted that the duplicate name restriction was eliminated back in July[1] and was just wondering if __proto__ is indeed a special case?

Thanks.
