Quantification of structural information: on a question raised by Brooks

We introduce the notion of 'generative software complexity' to illustrate some of the problems one may run into when trying to tackle a special case of a question recently raised by Brooks

Semantics of programming languages : a tool-oriented approach

By paying more attention to semantics-based tool generation, programming language semantics can significantly increase its impact. Ultimately, this may lead to ``Language Design Assistants'' incorporating substantial amounts of semantic knowledge

Rewriting-based languages and systems

Many systems are at least partly or implicitly based on term rewriting. Examples are functional languages, computer algebra systems, and theorem provers. We give a brief survey of these systems, and provide a more in-depth comparison of the features of systems that use term rewriting as their primary execution mechanism. We give links to rewrite tools and projects as well as pointers to notions and techniques covered in the preceding chapters
