Rastislav Lukac,Konstantinos N. Plataniotislculus of Abadi and Cardelli. Our primary contribution is to show that gradual typing and subtyping are orthogonal and can be combined in a principled fashion. We also develop a small-step semantics, provide a machine-checked proof of type safety, and improve the space efficiency of higher-order casts.

: Generalized Interfaces for Javan be solved more easily. .’s interface capabilities interact with subtyping (and subclassing) in interesting ways that go beyond type classes. . can be translated to Java?1.5. Its formal type system is derived from Featherweight GJ.

Jorge S. Benítez-Read,Daniel Vélez-Díazrency. We argue that it is impossible to make fault-tolerant systems using mutable shared state concurrency models. We explain the thinking behind what has become known as “Erlang style concurrency” and show the relation to Concurrency Oriented Programming. We take a brief detour and talk about the
