Languages for object-oriented programming
Relevant sections in text: 4.1
In this assignment, students assume the role of language designer, and consider issues in the design of languages for object-oriented programming by working with a version of the metacircular evaluator that has been extended to include classes, methods, and inheritance. The programming language used here is modelled on the Dylan language, and the extensions to the evaluator follow the approach described in The Art of the Metaobject Protocol, by Gregor Kiczales, Jim des Rivieres, and Dan Bobrow (MIT Press, 1991).This is a different object-oriented programming system than the one used in the object-oriented adventure game assignment.
Note: The construction of this assignment predates our final revison of the text for this second edition, so there are several minor differences between the code here and the metacircular evaluator as given in section 4.1. You may wish to update the code (notably some of the syntax procedures and data structures) before assigning this.
