Comment(by ncohen):
Because I sometimes stored them as keys of dictionaries. It means I will
need to forget to store the label, and just the endpoints. The other
detail is that in many algorithms, the labels are used as a weight, and I
you will see very often in Sage's code :
weight = lambda label : 1 if label is None else label
So all these occurrences need to be replaces to label == {} in this
case... Does that mean we should assume labels are ALWAYS dictionaries ?
This would mean trouble... Where would we store numerical values for edges
then.. a default field ?
