I watched some of the videos from the C++ conference at

Microsoft. Some of the advice given was to not use raw

pointers for ownership. I think that's going too far.

Someone may say that that doesn't scale if we need to

add another pointer to the class. I disagree. Classes

can have at least one pointer that isn't wrapped with

a smart pointer.

Finally, at the conference STL pointed out that using a

delegated constructor you can safely have multiple raw

pointers in a class:

Previously I was using unique_ptr more than now, but

have found in each of these cases that the code that

results without using it so much is a little smaller.

I've seen a lot of overuse of shared_ptr over the years

and now think it's also possible to use unique_ptr too

much.



The simplified advice came from Bjarne. I think for

student programs it doesn't make much difference, but

he may be focussing too much on beginners these days.
