Oh certainly. But a language in which there are "no immutable arrays" sounds more like it's oriented towards efficiency at the coding/debugging level, rather than the run-time level. Like Java and C#, which as >>23 mentions, act similarly.
But again: I know nothing about D; I was just suggesting a possible alternate interpretation of that code snippet from a few posts up, since at a guess, most people on this board know as little about D as I do.
