Developer Experience
Dependent types greatly improve the expressiveness of the language, allowing to write safer programs and making more illegal states unrepresentable. Scala supports dependent typing for its functional programming constructs — methods and functions. However, when it comes to the object-oriented side of the language, dependent typing with classes requires significantly more effort. In this talk, I will present new language features that further streamline using dependent types in Scala. Specifically, I will motivate the use of dependent types, explain how we handle dependent classes in the compiler, introduce the tracked modifier, and describe other improvements for tracking precise types.
I’m a first-year PhD student at EPFL. I have worked on many things Scala; this includes being part of the Scala 3 compiler team at VirtusLab, as well as EPFL LAMP’s Scala 3 research and compiler team. I also contributed to some Scala libraries and tools e.g. Scaladoc, quicklens, Inkuire
