I did notice some strange behaviour once, but things were working
without a problem for a while now.
foreach loops and concepts are nice concepts, which I'd like to carry on

Maybe somebody from the foreach-dopar packages could explain why they
have such issues?
Tim do you have concrete examples of the issues you talked with other
developers?
Thank you.
