D comes with a lot of "casual parallelism" baked in at the language level, and in its standard libraries. Actors are just one feature among many. You -can- explicitly manage threads and processes like in other languages, but much of the time there is a more lightweight, expressive construct available. For instance, you can turn this loop: foreach(ref i; arr) i = i * i; Into a parallelized loop by simply: foreach(ref i; parallel(arr)) i = i * i; Example was shamelessly lifted from: https://tour.dlang.org/tour/en/multithreading/std-parallelism https://tour.dlang.org/tour/en/multithreading/std-parallelis...
