Is there a way to do the following differently:

edge_x.a = np.array([x[e.source()] for e in g.edges()])

I plain English, is there a (more efficient) way to copy the vertex property map of every edge source to  an edge property map?
Something like this is not yet available, you have to use a python loop
for now.

However I plan to add something like this at some point, since it occurs
often enough. If you wish, you may open a ticket, and I'll address when
time permits.

Cheers,
Tiago
