A Theory of Tagged Objects (Artifact)

Authors: Joseph Lee, Jonathan Aldrich, Troy Shaw, Alex Potanin, and Benjamin Chung

Published in: DARTS, Volume 1, Issue 1, Special Issue of the 29th European Conference on Object-Oriented Programming (ECOOP 2015)

Abstract
A compiler and interpreter for Wyvern programming language written in Java and hosted on http://github.com/wyvernlang/wyvern and some sample programs (.wyv) including the main example from the paper in borderedwindow.wyv. We also include an extract of all the unit tests of which a large number may be designed to fail -- therefore they are best run using JUnit which can be done by checking out the source tree from the GitHub project link above.

A Theory of Tagged Objects

Authors: Joseph Lee, Jonathan Aldrich, Troy Shaw, and Alex Potanin

Published in: LIPIcs, Volume 37, 29th European Conference on Object-Oriented Programming (ECOOP 2015)

Abstract
Foundational models of object-oriented constructs typically model objects as records with a structural type. However, many object-oriented languages are class-based; statically-typed formal models of these languages tend to sacrifice the foundational nature of the record-based models, and in addition cannot express dynamic class loading or creation. In this paper, we explore how to model statically-typed object-oriented languages that support dynamic class creation using foundational constructs of type theory. We start with an extensible tag construct motivated by type theory, and adapt it to support static reasoning about class hierarchy and the tags supported by each object. The result is a model that better explains the relationship between object-oriented and functional programming paradigms, suggests a useful enhancement to functional programming languages, and paves the way for more expressive statically typed object-oriented languages. In that vein, we describe the design and implementation of the Wyvern language, which leverages our theory.
