The Tyranny of Types: Curse or Blessing?

Module IN0014, IN2107


Type systems play an essential role in the design of many programming languages. By classifying terms according to the kinds of values they compute, optimizations can be included, feedback can be provided to the programmer and certain run-time errors can be avoided. Beyond that, extended type systems have been proposed for program analyses on secure information-flow, resource usage or possible data races.

In this seminar we will examine a variety of type systems of modern programming languages and highlight some of their different concepts. In the course of that, we will discuss the advantages and limitations of static and dynamic type inference. Beyond that, we can take a look at some extended type systems that enable program analyses for other safety properties.


The seminar will be organized as a mini-conference. After submitting your draft paper you will be asked to review some drafts of your fellow students. The received feedback should be incorporated before submitting the final version of the paper. The final talks will be held en-block within two or three days at the end of the semester.
