I don't see how "logical" is confusing if people understand that it means the object stands-in for something else. A lowercase "a" does not stand in for an uppercase "A", so I wouldn't call it a logical "A".

The CGI.pm example just demostrates the hoops that Lincoln jumped through. Whether Mac Classic was right or wrong, it still was what it was. I didn't pick how these C libs were written or how these operating systems were designed. I'm not defending them. I just deal with it and get on with life.
