Classification: Honeywell Internal
Smart pointers (as in http://www.boost.org/doc/libs/1_56_0/libs/smart_ptr/smart_ptr.htm ) assume that the action you want to perform when the count goes to zero is to free the memory pointed to. That isn't the only use for reference counting. Why doesn't the Smart Pointer library decouple the reference counting from the action to be taken and provide a generic reference counting mechanism that will call an arbitrary function when the count goes to zero? The default can be "delete" to provide the expected memory management capability but it would provide a robust mechanism for those who need other capabilities.
Reviewing the code, it appears this decoupling already exists - through the use of boost::checked_delete and boost::checked_deleter (). It just doesn't appear to be documented. Why not document this so others know how to use it?
