[Xy-pic] loop in xy-pic (continued)

 Thanks to  Jürgen Koslowski, I realised that the problem is that I am trying
to use XY-pick with foils

 \documentclass[]{foils}

in this case, the diagram looks fine without loop, and does not accept loops
like

 \ar@(r,d)[]^{b}


 So the question is: is there a simple way to combine {foils} and {xy}?? Otherwise
is there a simple way to write overhead transparencies using XY-pick??
Thanks in advance for any help on this question.
