I'm afraid the memory management scheme might cause the Nimrod ecosystem to end up with too many libraries that require GC, and since the building blocks are already using it, why not use it yourself?<p>Either make it fully manual, or do something like Rust (No small feat). A GC you can switch on and off sounds like a good idea, but programmers don't keep half the promises they make ("It's just an MVP, I'll refactor it to use manual memory later").
