Tracking the state of an object (in the sense of how a File can be in an Open or Closed state) is difficult not just because of the problem of managing state transitions but also due to the complexity introduced by aliasing. Unchecked duplication of object references makes local reasoning impossible by allowing situations where transitions can be triggered(More)
The use of shared mutable state, commonly seen in object-oriented systems, is often problematic due to the potential conflicting interactions between aliases to the same state. We present a substructural type system outfitted with a novel lightweight interference control mechanism, rely-guarantee protocols, that enables controlled aliasing of shared(More)
