Actually, that's not a very good idea because the selector is not 
documentation. The compiler cannot ignore it.

With the Objective-C runtime, each function has a selector matching its 
actual Objective-C method name. The selector is what the compiler uses 
to call the function dynamically. The method name shouldn't be stripped 
like it was a comment or some documentation because that'll change and 
likely break the program.
