Abstract

A complete finite "algebraic" specification for a version of traversable stack with fewer error conditions is presented. This is used to illustrate some issues concerning formal specification of data types, namely naturalness and clarity. Uncontrolled errors are considered harmful and canonical-term specifications are considered helpful.
