Subject: How can I qualify the predefined logical operations

I have the following problem, when trying to implement a function "and".
package Some_Package is
type Private_Type is private;
function "And" (Left, Right: Private_Type) return Private_Type ;
private
type Private_Type is array (0 .. 1023) of Boolean;
end Some_Package;
-- I want to implement Some_Package."And" using the predefined logical
-- operation "And" for any one-dimensional array type whose components
-- are of a boolean type.
package body Some_Package is
function "And" (Left, Right: Private_Type) return Private_Type is
begin
return Left and Right; -- ERROR: AND is here Some_Package."AND",
-- endless recursive
end "and";
end Some_Package;
To fix the error in the implementation above, I need to qualify the
predefined "And" operation:
package body Some_Package is
function "And" (Left, Right: Private_Type) return Private_Type is
begin
return Standard."And" (Left, Right); -- ERROR: not possible
end "and";
end Some_Package;
How is it possible to qualify the predefined logical operations to
distinguish between Some_Package."and" and the predefined "and"?
Thanks in advance
