            // Differences from preparing Ruby method for update:
            // - No override search. 
            //   - We need to invalidate groups regardless of whether the e.m. overrides a method or not (it needs to be added to all groups below).
            //   - We could optimize a bit if the definition overrides a method group thata hasn't been used in a call site.
            //     In that case we wouldn't need to invalidate any rules. This is rare and we would still need to invalidate groups. So we don't do that.
            // - No CLR singletons special casing - extension methods can't be added on singletons.
