The Smalltalk-80 system offers a language with a small and elegant
conceptual core, and a highly interactive programming environment. We
believe, however, that it could be made more learnable and usable by a
relatively small set of changes. In this paper, we present the results of a
series of empirical studies on learnability, and also some informal studies
of large implementation projects. Based on these studies, we suggest a
number of changes to the Smalltalk-80 language and system.
