I prototyped these, and they work fine for reference types but fall 
apart for primitive arrays.  There *is* a Class literal for int.class, 
but we can't make it return an int[] with this method.  (This is one 
reason that Array.newInstance returns Object.)  Performance testing 
would be needed to ensure they are competitive with alternatives.
