Each node in a tree has a dictionary "sons", whose keys hold arc information, and values
are the son nodes. The question is to propagate a list of nodes to all their sons.
I use:

"from itertools import chain\nlist(chain.from_iterable(node.sons.values() for node in current_nodes))\n\nShould be faster. map and reduce on lambdas are slow. I don't know how fast chain is; you could try\nsum((node.sons.values() for node in current_nodes), [])\n\nas well.\n"
