I don't really "get" the sweet-spot being targeted here. You don't get channels, goroutines, or gc, so aside from syntax and spatial memory safety you're not really inheriting much from Go. There is also no pathway to integrate with existing Go libraries.
Spatial memory safety is nice but it's the temporal safety that worries me most, in nontrivial C codebases.
