Ownership types were devised nearly 15 years ago to provide a stronger notion of protection
to object-oriented programming languages. Rather than simply protecting the fields of an …

Language researchers and designers have extended a wide variety of type systems to
support gradual ty**, which enables languages to seamlessly combine dynamic and static …

Gradual ty** is a discipline for integrating dynamic checking into a static type system.
Since its introduction in functional languages, it has been adapted to a variety of type …

In security-typed programming languages, types statically enforce noninterference between
potentially conspiring values, such as the arguments and results of functions. But to adopt …

Parametric polymorphism and gradual ty** have proven to be a difficult combination, with
no language yet produced that satisfies the fundamental theorems of each: parametricity …

Bringing the benefits of gradual ty** to a language with parametric polymorphism like
System F, while preserving relational parametricity, has proven extremely challenging: first …

Both static and dynamic program verification approaches have significant disadvantages
when considered in isolation. Inspired by research on gradual ty**, we propose gradual …

Abstract Effect systems have the potential to help software developers, but their practical
adoption has been very limited. We conjecture that this limited adoption is due in part to the …

Gradual ty** allows programs to enjoy the benefits of both static ty** and dynamic
ty**. While it is often desirable to migrate a program from more dynamically-typed to more …

Ownership type systems describe a heap topology and enforce an encapsulation discipline;
they aid in various program correctness and understanding tasks. However, the annotation …
