I understand pros and cons of  in out for functions, but this one is really not convincing.
I always write:

while More_To_Come loop
   Get (Item);
   Do_Something (Item);
end loop;

Of course, Get raises an exception if there are no more items available, so it is a lot more secure.
Well, of course, security and exceptions are not an issue when you program in C...
