Abstract

This is like a tutorial implementation of object algebras in our language. Currently our compiler has no support for simple syntax of object algebras, so we have to design types by ourselves using simple constructors. In this talk, I'll show you how to implement algebra interfaces, queries and transformations, and how it works while still holding extensibility by using intersection types. An advanced feature is to have visitors for data structures, so as to save a lot of work in client code. Some more complicated examples will be available then, together with some discussions on pros and cons of programming in such a style, and prospects of designing syntactic sugar for algebras.
