I don't know the GP's reason, but I also orderd long aluminum profiles for LED installations (it's needed for heat dissipation, and also helped with mounting in my case).
Nix doesn't use most of C++ features though. It's just the way project was organized and code was formatted that it looked beautiful and easy to skim through.
