Abstract: 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 intend to extend this approach to arbitrary, gradually enforced contracts and investigate the language features necessary for their implementation.

Bio:

Grace

I am currently involved in the Grace programming language project, through the Hopper implementation of the language, as well as formalising the language’s semantics. You can find an online editor for Grace at grace/editor, and the Gribber music system (a Grace plugin for Gibber) at grace/gibber.

Haskell

I’m also an avid Haskeller. My most successful contribution is the http-media library, part of a larger attempt to simplify REST resources in the Snap web framework. I’ve tutored the Programming Languages (Haskell and Prolog) course at VUW for several years, as well as taught the Advanced Programming Languages course.
