Thanks, that's very interesting. Seems like it'd also be "interesting" to write a compiler for though, especially since you have to manage stack hygiene for four stacks simultaneously. And I'm not sure, but doesn't allowing each functional unit to directly read the top four entries of the other FUs' stacks reintroduce some of the kind of potential hazards that the Mill belt (with its SSA-style usage) tries to avoid?
