Objects declared inside (only) packages, as opposed to subprograms,
are equivalent to C's "static" -- they are allocated statically
rather than on the stack.  However, this presumes the size of
the array is known at compile-time.  If the size is not known at 
compile-time, the array may still end up on a "secondary" stack, 
or in the "heap," depending on the implementation.

You can also explicitly allocate an array in the heap using "new".
