| An array (well, collection) of ScratchObjects.
|
| This needs its own class, rather than using ScratchPrimitive, because resolve
| calls must recurse into the array in case there are object-references in the array
| (in fact, this is almost always the case).
|
| It is possible for entries in the array to be null, although the array
| itself should not be null.
