I don't think it is very hard: MemberExpression : MemberExpression . ( CascadeList ) ... CascadeList : Cascade CascadeList ; Cascade Cascade : PropertyName = AssignmentExpression PropertyName Arguments PropertyName .( CascadeList ) where all the non-terminals not explicitly specified above have there current (future) ES5/6 definitions. In particular: PropertyName : IdentifierName StringLiteral NumericLiteral @ Identifier //a hypothetical new addition for private name I don't yet love using parens in this way, but it seems that it could work for all of these cascade forms Allen
