That was the main reservation I had about the original patch. The way this could be problematic (apart from misleading documentation) is with non-simply laced types. So it is good that Anne tested C3~. My I suggest either qfolding and posting the patch or posting both patches to the trac server? I think Anne created the ticket #8811 for this purpose. I don't think the patch depends on anything else in the queue. Dan -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
