Extend protector naming code style guideline to cover RetainPtr with CF/ObjC types This is a logical extension of https://bugs.webkit.org/show_bug.cgi?id=157591 Allowed names should be like: RetainPtr<id> protectedSelf(self); RetainPtr<id> protector(view); RetainPtr<id> protectedView(view); RetainPtr<CFStringRef> protector(cfString); RetainPtr<CFStringRef> protectedCFString(cfString); A search through the current tree might also reveal common patterns with adoptNS and adoptCF that should also be accounted for.
