Comment (by vdelecroix):
I am waiting for the doctests... but what about
3) I am not convinced with
{{{
weight = lambda l : l if (l is not None and l) else 1
}}}
First of all as None evaluates to False, hence you can shorten it as
{{{
weight = lambda l: l if l else 1
}}}
which I definitely love ;-) On the other hand, it is not written anywhere
that if I put a weight 0 and set use_edge_labels=True then my 0 will
automatically become 1.
