But despite their fundamental importance, there are some common misconceptions about them, in particular about several of the most often used design patterns: - The modern form of the Visitor design pattern, std::variant, is often considered a replacement of virtual functions. - The Decorator design pattern is sometimes mistaken as the Adapter design pattern. - The Chain of Responsibility design pattern is often confused with Decorators. - Explicit object parameters (“deducing this”) is often named as a modern, better form of CRTP. In this talk I'll shed some light on these misconceptions and explain how to properly distinguish between the different design patterns.
