I used various modules with gc:none I meant that new ARC GC, that will replace the current one, can be used for the kernel. It's still a GC, technically, but, quoting Araq on ARC: Nim is getting the "one GC to rule them all". However calling it a GC doesn't do it justice, it's plain old reference counting with optimizations thanks to move semantics.
