Thank you for your interest! (I was away for the weekend...)

all the constraints are indexed,
remove_constraint takes as input the index of the constraint to be

Yes, and then? I don't think I can remove it again, can I?

So, what is the proper way to do it? As I wrote, it's not really an option
to solve the whole problem for each new constraint...
