The benefit of an @Override annotation (for e.g. as implemented in Java) is for the compiler to warn you if you're not actually overriding something when you think you are. Which could happen if the superclass changed since the time you wrote the code or if you made a typo in the method name/signature.<div>

If so, the parsing isn't the hard part, you'd need to mangle selectors somehow, and enhance the runtime to support this. This isn't something we want in ObjC, because want to keep it simple.</div>
