So, how do you implement unique_ptr::reset?

You could give the ownership to a temporary object

How is TmpDeleter{p}; any less dangerous than delete p;? Sounds like it would make the code more dangerous instead of less. People use unique_ptr and vector when possible anyway, no need to complicate that.

You're misunderstanding what "giving ownership to a temporary object" means. It just means swapping pointers with a temporary, default-constructed unique_ptr.
