Hello,

I'd love this too, but I'm not sure what would be the static code 
validation behavior, knowing that you can rename methods of traits when 
using them in a class: should the trait method not be validated ? Should 
the final class be validated after the trait has been used, meaning that 
if a method name change, the final class must re-implement it ?
