We should at least have a rules stating "pay attentino you use an optimised selector". Im not sure what should be form of the warning but we should make progress


why? 

I see two cases
   - the dev uses a non optimized version and the warning tell him that it would be better to use the optimised
   ifNil....of whatever case

   - when defining a method with such selector:
   warn them because we should avoid them.



I somehow feel that I did not manage to explain the whole thing in a way that it was understandable.
Can we discuss that on the whiteboard next week?
