We seem to have acquired a cardinality() function with almost no discussion, and it has semantics that are a bit surprising to me. I should have thought cardinality(array) would be the total number of elements in the array. Instead, it seems it is a synonym for array_length(array,1). Is that *really* what the standard says?
