I am stunned! Since I try to make my code working for both PHP4 and PHP5
I try to never rely on PHP4's standard cloning behaviour, and use &
where I can, so I have never really encountered this, but this will

goodbye to PHP4. (I remember when I first encountered the 'references in
constructor'-issue)
excellent stuff!
