I don't think we need that much magic ;)

We do not need the actual class and selector of the method that sent  
#translated. Class category is sufficient for the lookup, right?

We know thisContext sender's class already, so the right class  
category must be the category of the sender's class, or one of its  
superclasses. That should be sufficient and reasonably fast, since I  
doubt there would be more than two or three different class  
categories involved in a given superclass chain.
