Overview:

Higher-Order Abstract Syntax (HOAS) is a simple, powerful technique for implementing object languages, since it directly supports common and tricky routines dealing with variables, such as capture-avoiding substitution and renaming. This is achieved by representing binders in the object-language via binders in the meta-language. However, enriching functional programming languages with direct support for HOAS has been a major challenge, because recursion over HOAS encodings requires one to traverse - abstractions and necessitates programming with open objects. The paper presents a novel type-theoretic foundation based on contextual modal types which allows one to recursively analyze open terms via higher-order pattern matching. By design, variables occurring in open terms can never escape their scope.
