[issue643841] New class special method lookup change

Hi, I was trying to implement a generic proxy class with some
restricting behaviors and then I bumped into this complication.  May I
ask what the conclusion is going to be in the long run? 

I guess my question is that 

1> is it just going to be a documentation change (first)?

2> is it technically difficult(other things are going to be broken
because of this change) or very inefficient to make the behavior of
special method lookup same as normal methods?

2> Otherwise, what is the rationale behind keeping the differences? 

thank you.
