I like the way how you think but real compilers don't do what you say these *should*. So the subtle issue is still very real. > ^ > This makes the compiler generate a copy ctor according to > a deprecated rule. I would also love warning, but it is tricky to make good suggestion how to achieve that it does not look rather confusing. For example when the above 'indirect_int' is used as member in a class made by rule of zero and then object of that class is copied. > Unforunately, last time I checked, no compiler would actually issue a > warning in such a case in C++11 mode. :-( Things could be so much > simpler for beginners... Yes. Neither in C++11 nor in C++14 mode. The vendors of compilers interpret that deprecation somehow differently and so we have to keep enforcing safe usage with our coding standards. |
