Re: [boost] Is there any interest in non-owning pointer-like types?

For me, the biggest problem of the proposal is that observer_ptr<T> is implicitely constructed from T&. In my code I often use:

Foo a; Bar b(&a);//&a signals that b only references to a, but does not copy it.

Now, when I write

Bar b(a); //so is a now copied?

While the interface is clearer in documentation, the usage is less clear!

IMO using pointers instead of references to indicate something isn't copied is bad practice.. the language is C++, not C. -- Olaf
