could you explain what those advantages are?
a scoped_ptr can't be copied at can't be moved. so there are two use cases
left for a scoped_ptr deleter:
- scoped_ptr as a class member: execute code when the class gets
destructed -> that's what a destructor is for.
- scoped_ptr as a local variable, execute code when something goes out of
scope -> that's what boost ScopeExit is for.
what is the use case that only a scoped_ptr deleter can handle?
