Surely you don't mean (forgive me if Deja decides to throw away my
formatting):

function Next_Line return String is
   Char : Character;
   Next_Char : Character;
   EOL  : Boolean;
begin
   Get (Char);
   Look_Ahead (Next_Char, EOL);
   if EOL then
      return (1 => Char);
   else
      return Char & Next_Line;
   end if;
end Next_Line;

I think we may have just smoked out a Lisp programmer...
