If it was chainable you could use it to do poor man’s mixins. But the requirement that the rhs be an object literal prevents chaining. Otherwise, you would have to define some kind of clone operation for intermediate lhs operands. -- Dr. Axel Rauschmayer [email protected] home: rauschma.de twitter: twitter.com/rauschma blog: 2ality.com
