How do we handle single-dimensional arrays of composite types at the

treated like strings, when they're in an array. That's probably OK, but
it means that there's nothing special about composite types in
multi-dimensional arrays. In any case, we should mention that in the docs.

That is how they're handled, but I'd really like to change that. I've held off because I don't know how to handle the backwards incompatibility that would introduce. (I've been wondering if we might add a facility to allow specifying default TRANSFORMs that should be used for specific data types in specific languages.)

The converse case (a composite with arrays) suffers the same problem (array is just treated as a string).
