I can second this. I was planning on making a library that wraps a few C libraries with seamless async and wanted a language that would work well in that context. Tried out Rust and really struggled to get something going, switched to Nim and had something up and running within minutes. So much easier. But as my work continued I ran into other roadblocks: bad documentation, small community. I went back to Rust, stuck with it, and now I'm very happy using Rust. But if you're looking for something low-level that you can pick up super-quickly, Nim is awesome. And the executables are crazy small, even compared to Rust.
