ECOOP 2015
Sun 5 - Fri 10 July 2015 Prague, Czech Republic
Wed 8 Jul 2015 16:00 - 16:30 at Bohemia - Objects Chair(s): Kim Bruce

Combinations of structural and nominal object typing in systems such as Scala, Whiteoak, and Unity have focused on extending existing nominal, class-based systems with structural subtyping. The typical rules of nominal typing do not lend themselves to such an extension, resulting in major modifications. Adding object branding to an existing structural system integrates nominal and structural typing without excessively complicating the type system. We have implemented brand objects to explicitly type objects, using existing features of the structurally typed language Grace, along with a static type checker which treats the brands as nominal types. We demonstrate that the brands are useful in the existing implementation of Grace, and provide a formal model of the extension to the language.
