Snippet
```c++
template <class T>
class Base {
  friend T;
  Base() = default;

 public:
  Base(const Base&) = delete;
  Base& operator=(const Base&) = delete;

  Base(Base&&) = delete;
  Base& operator=(Base&&) = delete;

  ~Base() = default;
};

class Foo : public Base<Foo> {};
```

produces 
```
warning: public contructor allows the CRTP to be constructed as a regular template class; consider making it private [bugprone-crtp-constructor-accessibility]
```
