Knowledge of unique ownership can obviate the need for copying, but copying is a reasonable fall-back in most cases. > Also, parallel map/foreach is more feasible as a library-only solution, > whether the message passing requires some support from the runtime > environment. It really depends on the language and what your goals are. There are message passing libraries for C, for example, but they don't provide much in the way of safety.
