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?

cheers
