Benchmarking enum-to-string conversion: C++26 reflection vs traditional approaches

Summary

This article benchmarks the compile-time cost of C++26 reflection features (specifically enum-to-string conversion) compared to traditional approaches like macros and manual code. Building on a previous article about GCC 16 reflection costs, the author uses enum-to-string as a practical "hello world" example of reflection. The article measures compilation time and binary size trade-offs between the new reflection-based approach and older methods, providing performance data for C++ developers evaluating whether to adopt C++26 reflection features.
