I come to judge language's quality of documentation almost solely on their documentation around local and module imports. If they don't provide clear documentation on that subject, which is paramount imo to getting past simple scripts, then the rest of their higher level documentation is probably lacking. I've been upgrading some personal Go projects I have to a more modern folder layout (pkg, internal, etc. vs. src folder) and I really found their documentation lacking. Rust for example, in their imports, is so so, but I've found way better external examples for imports in Rust than Go.
