That's the equivalent of D's static arrays if a variable, and is 
passed to C functions as a pointer. So important to note it is 
two different beasts in different contexts.

I recently wrote about this here:
https://forum.dlang.org/thread/uhibzcfwzqzqqfbrckup@forum.dlang.org

so read that post for some more detail, especially with relation 
to `extern` variables.

address of first element for that, but if you are using a 
built-in D array, you can also just `arr.ptr`.
