Lennart Augustsson is a Swedish computer scientist. He was previously a lecturer at the Computing Science Department at Chalmers University of Technology. His research field is functional programming and implementations of functional languages.
Augustsson is the author of:
- The Cayenne programming language.
- The HBC Haskell compiler.
- Several hardware device drivers for NetBSD.
- The front end of the pH compiler (parallel Haskell) from MIT.
- The initial version of the Bluespec compiler.
He was also a co-developer, with Thomas Johnsson, of Lazy ML, a functional programming language developed in the early 1980s, prior to Miranda and Haskell. LML is a strongly typed, statically scoped implementation of ML, with lazy evaluation. The key innovation of LML was to demonstrate how to compile a lazy functional language. Until then, lazy languages had been implemented via interpreted graph reduction. LML compiled to G-machine code.
Augustsson has written three winning entries in the International Obfuscated C Code Contest:
- 1985: Most obscure program (1985/august.c)
- 1986: Best complex task done in a complex way (1986/august.c)
- 1996: Best of Show (1996/august.c)
