The code below illustrates my dillema.

package Test is

    -- why not: 'type Door is protected'?
    -- Is this because protected_type_declaration 
    -- is supposed to resemble task_type_declaration?

    protected type Door is
    
        procedure Open;
        procedure Close;
        function Can_Go_Thru return Boolean;
    
    private
    
        State: Boolean := False;
    
    end Door;

    
    type Door_Nogo is record 
    
        -- can't put function / procedure here?
        -- procedure Open;
        -- procedure Close;
        -- function Can_Go_Thru return Boolean;
    
        Status: Boolean := False;

    end record;

end Test;

I have two more questions:
1. Is there something like super in Java?
2. Can I overload () operator? I guess no.

Thanks for pointing me at collection class libraries, although I am a
bit overwhelmed by the wealth.
