When version 4 was being put together one of things we decided to do was
try to clean up the implementation and support for arrays.  Our time ran
short and we did not manage to finish everything.  The painful way to get
multi-dimensional arrays (outlined in the manual) was removed and we didn't
get a chance to do the clean implementation.

As of 4.0 only single dimensional arrays are supported. Sorry.

This seems kind of fishy.  I will look into it.
