I haven't written c++ seriously for a number of years. Do you still have to do all that "rule of three" boilerplate stuff to use your classes with the STL? Is it better or worse now with move constructors?
class Class
{
Class();
Class(const Class&) = delete;
Class& operator = (const Class&) = delete;
~Class() = default;
};
Move constructors are an extra that, if I remember correctly, don't get a default version, thankfully.
