At least it seems to be an important starting point if we are to take categorical programming within the Hagino style seriously. The "et al." group includes Tom Fukushima who has actually implemented such a CDT programming language (CHARITY) with initial and final datatypes, and myself, whose thesis - "Categorical Programming with Functorial Strength" that expounds on much of the categorical underpinnings of this language - will be completed within the next month or so. The parallels with Malcolm's syntactic calculus are very strong (not a pun) and the variety of datatypes available to the programmer is quite reasonable for much practical programming (e.g. database applications). - Dwight Spencer Oregon Graduate Institute --> Trinity College, Hartford, CT
