More options are always welcome, so long as they're easy to specify.
Incidentally, I believe there was a problem with placing edge_index_t edge_index in the bundled properties----it only worked when I used the (far uglier) joint internal/bundled property approach. Something else to put on the list.

Me neither. This is really my first time digging into subgraph. It makes
sense (to me) that each vertex/edge should have only one property, but I can
see reasons for localizing properties as well. If both are needed, I can
create specializations of property_map that select local/global lookup
strategies. Would that be acceptable?
