So you pay the price of some performance for such increased flexibility. The idea here is that the built-in data types must be as flexible as possible even if their performance is not so high, so they can be used for many different purposes. Then D standard library will have specialized data structures that are faster thanks to being more specialized and less flexible. In D dynamic arrays some of the performance price is also paid for the automatic memory management, for the GC that's not a precise GC (for example if your array has some empty items at the end past its true length, the GC must ignore them).
OTish: It would be nice if the data-structures-to-be are designed such
that they can be easily dropped in wherever dynamic arrays are used. At
least the list-like ones.
