Type Soundness for Dependent Object Types (DOT)

Tiark Rompf, Nada Amin

Scala's type system unifies aspects of ML modules, object-oriented, and functional programming. The Dependent Object Types (DOT) family of calculi has been proposed as a new theoretic foundation for Scala and similar expressive languages. Unfortunately, ty ...

Towards Predicting Success in MOOCs: Programming Assignments

Pierre Dillenbourg, Patrick Jermann, Kshitij Sharma, Lukasz Kidzinski

Students of programming languages in massive on-line open courses (MOOCs) solve programming assignments in order to internalize the concepts. Programming assignments also constitute the assessment procedure for such courses. Depending on their motivation a ...

Auto-Collections for Scala

Dmytro Petrashko, Allan Vincent Roger Renucci

Modern programming languages such as Scala, Java and C# make extensive use of collections. A collection implementation represents a fixed choice in the dimensions of operation time and space utilization. Using the collection in a manner not consistent with ...

Translating Scala Programs to Isabelle/HOL, Automated Reasoning

Viktor Kuncak

We present a trustworthy connection between the Leon verification system and the Isabelle proof assistant. Leon is a system for verifying functional Scala programs. It uses a variety of automated theorem provers (ATPs) to check verification conditions (VCs ...

Semantics-Driven Interoperability between Scala.js and JavaScript

Sébastien Jean R Doeraene, Nicolas Alexander Stucki, Tobias Schlatter

Hundreds of programming languages compile to JavaScript. Yet, most of them fail, at one level or another, to provide satisfactory interoperability with JavaScript APIs. This is limiting, as interoperability is at least required to manipulate web pages thro ...

Java and Scala's Type Systems are Unsound: The Existential Crisis of Null Pointers

Nada Amin

We present short programs that demonstrate the unsoundness of Java and Scala’s current type systems. In particular, these programs provide parametrically polymorphic functions that can turn any type into any type without (down)casting. Fortunately, paramet ...

Style Checking With Scala.Meta

Eugene Burmako, Mathieu Baptiste Demarne

In many companies, code reviews are big parts of the day-to-day life of an engineer. Some can argue that the time spent on someone else’s code is time that some cannot spent on her or his own work. Code reviews usually allow to find two kinds of issues. Th ...
