This will always be invalid regardless of how nil is handled, because  
you cannot add two pointers together. You can add integers to pointers  
though, so the question is about "nil + 1" and the like. Delphi indeed  
gives an error, which makes sense. I resolved the internalerror by  
accepting the expression, which is indeed not a good idea. So I'll  
change it.
