A nice consideration on value semantics and STL/boost algorithms: In generic implementations of algorithms it is preferred to use value semantics: copying an object causes two identical objects to exist which are independent. This is crucial property when it is necessary to duplicate objects. Dynamic polymorphism doesn't immediately work…
