We present the meta-theory behind the code generation facilities of Isabelle/HOL. To bridge
the gap between the source (higher-order logic with type classes) and the many possible …

ML modules and Haskell type classes have proven to be highly effective tools for program
structuring. Modules emphasize explicit configuration of program components and the use of …

We describe deriving, a system of extensible generic functions for OCaml implemented as a
preprocessor and supporting library. We argue that generating code from type-definitions …

Researchers repeatedly observed that the module system of ML and the type class
mechanism of Haskell are related. So far, this relationship has received little formal …

We propose an Haskell-like language with the goal of unifying type classes and generalized
algebraic datatypes (GADTs) into a single class construct. We treat classes as first-class …

Haskell is a very in uential functional programming language with an advanced type system
that is capable of detecting many bugs. In this dissertation, we are interested in situations …

Avoiding introducing bugs, and limiting their impact when they are introduced, are key
challenges for the software industry today. Formal verification offers hope in this endeavour …
