Concepts of Programming Languages is a course that introduces students to some fundamental concepts in programming language design and implementation. The primary goal is to allow students who complete this subject to have a good feel for the elements of style and aesthetics of programming and a good command of the major techniques for controlling complexity in programming.

ATS is a programming language that makes pervasive use of types in capturing programming invariants. We will be learning how datatypes in ATS can be used to conveniently model data structures and how pattern matching can be used to facilitate programming with datatypes. Also, we are to make extensive use of abstract types in the construction of (relatively) large and complex programs.

Ultimately, we would like to make a convincing argument that programming can be a great deal of fun if you do it the right way!
