Re: Visibility in embedded packages

Only the third method:
  package Operators
   function "+"(Left, Right : Integer_Type) return Integer_Type
      renames Standard_Types."+";
   . . .

is correct.
This is because that the declaration of "+" in
package Operators hides the outer declaration of "+" in Standard_Types,
requiring the expanded-name notation.

The version which requires Standard."+" is totally wrong,
since the Integer_Type is not declared in package Standard.
