If you want to read an interesting thread go look for any of the threads 
here about the difference between null and "", e.i. a null array and an 
empty array. People around here have come up with many good reasons to 
maintain that distinction, and I expect, if asked, can come up with just 
as many good reasons to maintain the distinction between a single 
element array and a single element.
