Thy aren't hidden: when you grow a dynamic array you know an allocation generally takes place. If you don't want reallocations, then never grow or join them, and the reallocations will not happen. There's nothing hidden.

I agree, it's something that I think is quickly understood by newcomers to the language. It's the same problem as string concatenation in C# and Java, where the common idiom is to use StringBuilder. I have seen such builders floating around in the ng, but is it phobos or tango already?
