type POINTER is access all INTEGER;
Long: POINTER
declare
   Local: aliased INTEGER := -42;
   SHORT: POINTEUR := LOCAL'Access;
begin
   Long := LOCAL'Access;
end;
...Long is a dangling reference after the "end", but SHORT never becomes one. Why must SHORT := LOCAL'Access be forbidden, can't the compiler see that no assignation to outliving variable can happen ?
