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
In programming language theory, lazy evaluation, or call-by-need, is an evaluation strategy which delays the evaluation of an expression until its value is needed ( non-strict evaluation) and which also avoids repeated evaluations (sharing).
The ...
. 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 was intimately involved in early ]LPMud

Augustsson has written three winning entries in the International Obfuscated C Code Contest:

* 1986: Best complex task done in a complex way
* 1996: Best of Show
