Are you saying that on a compiler where an operation on optional might give wrong run-time result, the operation should be disabled (render a compile-time error)?

I think that am I saying that if an operation on optional is apt to result in dangling pointers on many popular compilers, the operation should be disabled for all compilers for consistency, not just those that will exhibit the failure. This interface is obviously too dangerous to be of any use and, while it will work on some compilers, its use will not be portable.

It's also possible to make the feature optional, so that it can be enabled by a macro.
