I have something a bit different, I don’t know if it fits here.
I asked a question on StackOverflow: What are the similarities and differences between C++'s concepts and Rust’s traits? I know a lot of people that are really interested in an answer to it. @matthieum already attempted to answer it (which I am very happy about), but they mention that they have not yet worked with concepts " so take this answer with a grain of salt.".
It would be cool to maybe find someone who really knows C++ concepts to answer this question. So I thought that we can maybe add this to TWiR to reach a wider audience? Something like:
Do you know a lot about C++ concepts? Please consider answering this question or improving existing answers (e.g. by pointing out flaws): What are the similarities and differences between C++'s concepts and Rust’s traits?
I will also add a bounty to the question in a few days (before the next TWiR is released).
