Is the mut marking also for consistency (and/or non-message methods)? Presumably each actor/object would only process one message at a time so could always have full access to all its data.
One more question, is memory allocated globally or from arenas/slabs/etc?

I always felt that Rust wasn't a local maxima and there was something that could be added/removed. The only thing I'm not sold on is async (outside of actor use) vs futures where waiting explicitly blocks the waiter, but can be composed without waits. There seems to be some debate around Rust's choice of implementation.
