You can certainly write very low-level Nim code though, seeing that things like Arraymancer (high-performance tensor library) and Chronos (an async runtime) are written in pure Nim. Everything you can do in C you can certainly do it in Nim (event better, with generics/templates/macros helping you out). And once the garbage collector is finally removed for the new ARC/ORC runtime (think of Objective-C-like reference counting, but much better), it’s definitely a language that can compete with C++/Zig/Rust.
