Why doesn Chic add a copy constructor and an assignment operator to my class?
A C++ compiler generates a copy constructor and an assignment operator only if they’re actually called. It’s legal and common to have a class that cannot be copy constructed or assigned as long as you don’t try to perform any of these operations. As Chic cannot know whether or not you’re going to copy construct or assign your class, it takes a conservative approach and assumes you will not do either.
