Why is my Rust build so slow?
This much complexity and the tribal knowledge required to bypass it, so early in the the life of a programming language, is a really bad sign.<p>It means the complexity of the problem space is not solved by the language, and the responsibility of solving it is being passed on to the users.<p>You might react to this by saying that slow build times are not a big deal. That's a mistake -- iteration is key to productivity and other languages do it better.
