Cool! I was referring to the bug declared at the top of this page [1]. Is that warning obsolete?

Apart from the theory that whole website is pretty much obsolete.

Indeed, I did look at FGL. It's beautiful. It has a bug that does not permit multiedges in directed graphs, which I need.

What do you mean by "multiedges"? Multiple edges between two nodes? If that's the case, PatriciaTree used to have this problem, but I fixed that way back in 2010 when I first took over maintainership of fgl.
