Despite the long history of research in parsing, constructing parsers for real programming
languages remains a difficult and painful task. In the last decades, different parser …

Layout-sensitive grammars have been adopted in many modern programming languages. In
a serious language design phase, the specified syntax—typically a grammar—must be …

Extensible programming languages such as SugarJ or Racket enable programmers to
introduce customary language features as extensions of the base language. Traditionally …
