I don't know what is wrong with you guys. SW design can be good even if it has 
interdependent classes. It depends on the original problem scope.
This is from Michael's other mail:

Right, so the original comment
 "In more than 20 years of pascal programming, I never encountered this 
problem."
actually means to copy everything into one file.
That's what I was saying, too! :-)

If I understand right, Michael and Mattias have made big parts of Lazarus core 
which I referred to. They have used types casting to avoid circular 
references. Now they say they never encountered this problem.
It is like:
  "We never encountered a problem. We just typecast everything! Hey no 
problem!"

Funny :-)
