Live programming environments aim to provide programmers (and sometimes audiences)
with continuous feedback about a program's dynamic behavior as it is being edited. The …

With distributed computing becoming ubiquitous in the modern era, safe distributed
programming is an open challenge. To address this, multiparty session types (MPST) …

We propose a type system for functional languages with gradual types and set-theoretic type
connectives and prove its soundness. In particular, we show how to lift the definition of the …

We define a new, more semantic interpretation of gradual types and use it to``gradualize''two
forms of polymorphism: subtyping polymorphism and implicit parametric polymorphism. In …

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 typing 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 typing to a language with parametric polymorphism like
System F, while preserving relational parametricity, has proven extremely challenging: first …

The literature on gradual typing presents three fundamentally different ways of thinking
about the integrity of programs that combine statically typed and dynamically typed code …

Sandboxing is a common technique that allows low-level, untrusted components to safely
interact with trusted code. However, previous work has only investigated the low-level …

We investigate gradual variations on the Calculus of Inductive Construction (CIC) for swifter
prototyping with imprecise types and terms. We observe, with a no-go theorem, a crucial …
