In after C++11 std::vector, it defines data() function to retrieve internal data. http://www.cplusplus.com/reference/vector/vector/data/ It would be a convenience to make it available in std.container.array.Array as well, with @system and a clear indication that dangling is a possibility. This feature is useful for making simple dump files and interfacing with C. Also, in the case of simple byte sequence memory operations, it is expected to be faster than Range.

You can use (&arr[0])[0 .. arr.length].
