Formal foundations for GADTs in Scala

GADTs are a very useful language feature that allow encoding some invariants in types. GADT reasoning is currently implemented in Scala and Dotty, but it’s plagued with soundness issues. To get a better understanding of GADTs in Scala, we explore how they ...

Towards Improved GADT Reasoning in Scala

Lionel Emile Vincent Parreaux, Aleksander Slawomir Boruch-Gruszecki, Paolo Giosuè Giarrusso

Generalized algebraic data types (GADT) have been notoriously difficult to implement correctly in Scala. Both major Scala compilers, Scalac and Dotty, are currently known to have type soundness holes related to them. In particular, covariant GADTs have exp ...

Cross-Platform Language Design

Sébastien Jean R Doeraene

Programming languages are increasingly compiled to multiple runtimes, each featuring their own rich structures such as their object model. Furthermore, they need to interact with other languages targeting said runtimes. A language targeting only one runtim ...

Higher-Order Subtyping with Type Intervals

Sandro Stucki

Modern, statically typed programming languages provide various abstraction facilities at both the term- and type-level. Common abstraction mechanisms for types include parametric polymorphism -- a hallmark of functional languages -- and subtyping -- which ...

Call Graphs for Languages with Parametric Polymorphism

Martin Odersky, Vlad Ureche, Dmytro Petrashko

The performance of contemporary object oriented languages depends on optimizations such as devirtualization, inlining, and specialization, and these in turn depend on precise call graph analysis. Existing call graph analyses do not take advantage of the in ...

Compile-Time Type-Driven Data Representation Transformations in Object-Oriented Languages

Vlad Ureche

High-level languages allow programmers to express data structures and algorithms that abstract over the type of data they handle. This improves code reuse and makes it possible to develop general-purpose libraries. Yet, data abstractions slow down program ...

Additional Material for "Unifying Data Representation Transformations"

Vlad Ureche

This report shows an attempt to formalize the data representation transformation mechanism in the ``Unifying Data Representation Transformations'' paper. Since the mechanism described in the paper is targeted at the Scala programming language and the speci ...

Instant Pickles: Generating Object-Oriented Pickler Combinators for Fast and Extensible Serialization

Martin Odersky, Philipp Haller, Eugene Burmako

As more applications migrate to the cloud, and as “big data” edges into even more production environments, the performance and simplicity of exchanging data between compute nodes/devices is increasing in importance. An issue central to distributed programm ...

Quasiquotes for Scala

Martin Odersky, Eugene Burmako, Denys Shabalin

We introduce quasiquotes for the Scala programming language, which solve the problem of manual tree construction and deconstruction. Included case studies show that quasiquotes indeed are easier to work with than existing tools for tree construction. When ...
