Correct. I'd add that with ARC (or ORC even), there's little reason to do manual memory management (alloc/free), even for embedded systems. ARC is an automatic memory management system based on reference counting, but there's no "runtime". It actually injects alloc and free calls at compile-time based on static analysis. ORC adds runtime GC only for cycles, and will be the default in Nim 2.0.
