Do I miss the point?
Shouldn't have "new int[0]" , "[]" , ".length = 0" and "null" the 
same meaning like "array is empty"? I never understood why [] and 
null have different meanings in other languages.

And following the discussion...In my mind, aren't pointer 
operations dangerous?...yes,sometimes necessary...but always like 
an operation on a open heart.
