I totally agree that is all about balancing. I wrote exactly the same thing as part of my previous e-mail (before reading this message). Are you concerned by the cost the of function calls or by the "verbosity" in calling them? If it's about their cost, I believe that cold code paths like these, where the program is just parsing its command line arguments, it seems absolutely OK to me to do that. It's a one-time thing before any kind of tracing starts. And it helps a lot contributors to better understand the code (in my opinion). Otherwise, I believe that having those function calls that way just makes the code simpler for new contributors. Functions, among everything else, are also "labels" for pieces of code. Having two different labels there (init context and parse options) makes sense to me. But, again, I understand that is a trade-off based on my subjective value system and way of thinking, of course. Do you have a strong opinion? Vlad
