I suspect it'd be quiet, unfortunately, since there are a bazillion ad hoc implementations of a Perl SQL array parser,
andmany of them, I suspect, don't complain if the string doesn't look like an SQL array. They would just parse a string
like"ARRAY(0x118ee2a0)" and return an empty array, or a NULL.
