then maybe it should say: > a 2-tuple like structure that stores cubes in each slot. instead of > a 2-tuple like structure that stores cubes in two slots. The flowing also confused me: > It allows us to store a value and resolves concurrently set values by keeping both values. "both" indicates the concurrency can only happen between two parties. I think saying "keeping all values" is more accurate.
