Lambda the Ultimate

Combining the actor-model with shared memory for per- formance is efficient but can introduce data-races. Existing approaches to static data-race freedom are based on unique- ness and immutability , but lack flexibility and high perform- ance implementations. Our approach, based on deny prop- erties , allows reading, writing and traversing unique refer- ences, introduces a new form of write uniqueness , and guar- antees atomic behaviours .
