Some of the principal objectives are presented and justified. The means employed to express behaviour are then described, including a transfer primitive, which conveys object ownership as well as value, and an alternation construct. The latter replaces PRI PAR and PRI ALT, and affords explicit expression of conflict-free prioritized reactive (event-driven) behaviour, including exception response. HPL also offers source-code modularity, object encapsulation, and the recursive definition of both object and process. Despite such ambition, a primary aim has been to retain simplicity in abstraction, expression, and implementation." }
