Dynamic arrays in D are "fat" pointers, they have a .ptr and .length, but scanf expects C-style bare pointers, so you have to specify .ptr in order to pass the pointer to scanf. Be aware, however, that doing this means you no longer have D's bounds-checking protection, and scanf may cause buffer overruns if the user gives bad input.
