CRTP static polymorphism
The Curiously Recurring Template Pattern (`class D : public Base<D>`) enables:
Options
- 1Runtime polymorphism that is faster than virtual functions because it uses a special vtable.
- 2Static (compile-time) polymorphism, letting Base cast `this` to D& and call D's methods without a vtable.
- 3The complete prevention of all inheritance from the derived class, sealing it as final.
- 4The automatic generation of a virtual destructor for every class in the CRTP hierarchy.
