32_CRTP - Static Polymorphism for better performance

[MarioGalindoQ]

Overview

The Curiously Recurring Template Pattern (CRTP) is a powerful C++ idiom for achieving static polymorphism. Unlike traditional virtual functions, CRTP resolves calls at compile-time, eliminating the overhead of the vtable.

Discussion points

I'd love to hear your experience with this technique:

1. Compilation Time: While CRTP is faster at runtime, it can increase build times. Have you found this to be a significant issue in large projects?
2. Code Readability: CRTP syntax can be intimidating for beginners. Do you think the performance gain is worth the added complexity compared to standard inheritance?

Is CRTP your first choice for high-performance libraries, or do you prefer other modern alternatives like std::variant? 💻
