<p>This paper summarizes three discussions conducted at the ECOOP'91 W5 Workshop on ''Types, Inheritance, and Assignments'' Tuesday July 16, 1991 in Geneva, Switzerland, organized by the authors.</p><p> </p><p>The three discussions were entitled ''Classes versus Types'', ''Static versus Dynamic Typing'', and ''Type Inference''. All these topics were assumed to be volatile and controversial; indeed, a broad range of diverging opinions were represented. However, much superficial disagreement seemed to be rooted in confusions about terminology. When such issues were resolved, there appeared a consensus about basic definitions and the - often incompatible - choices that one is at liberty to make. This clarification, which we hope to have described below, was the most important achievement of the workshop.</p>
