Static arrays (`T[N]`) are value types, like structs. If you 
declare them as local variables, they're allocated on the stack.

Dynamic arrays (`T[]`), also known as slices, are reference 
types, consisting of a pointer and a length. If you declare them 
as local variables, the pointer and length will be stored on the 
stack. The data they point to, however, may be stored on either 
the stack or the heap.

For more information about slices in D, I highly recommend this 
excellent article by Steven Schveighoffer:
