In  Fairbairn and Wray introduced TIM, a simple abstract machine for executing supercombinators. Their abstract machine is an elegant design optimised for normal order evaluation. However, the addition of a mechanism to implement lazy evaluation considerably increases its complexity and imposes a signicant overhead.
We originally made this observation in March 1989, when a draft of this paper was circulated privately. Since then, there have been a number of publications about TIM (see, for example, [1, 10, 8]). Inevitably, some of the ideas presented here have been invented independently, orhave been improved upon in these subsequent publications. However, we feel our central idea for optimising partial applications in TIM has still to gain the attention that it deserves.
