Does the standard library use malloc/free or does it depend on the GC? This is the part that's puzzling to me, if the stdlib depends on GC then it's harder to say that GC is optional. Technically optional but not super practical.
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.
