// I've created this file to try to reproduce the results in this blog.
// This little program was timed with Measure-Command { a.exe 9999999 | Out-Default } repeatedly
// and compiled with Clang 16.0.0 x86_64-pc_windows-msvc with the command clang++.exe -std=c++17 -O3 cleancodebench.cpp.
// On my hardware and operating system Ryzen 7 5800X and Windows 11 I couldn't reproduce the results.
