Except that containers shouldn't provide indexing if it's not efficient. And from what I've seen, it's far too common for programmers to check length == 0, and they end up doing it on stuff like linked lists where it _is_ inefficient. It's considered good practice in C++ to use empty rather than length for exactly the reasons that I've listed. D is no different in this regard.
In D it's poor style to define linear-time length. That's called walkLength. Andrei
