just so i'm clear, this value is no longer in the output because vadas (aka
`v[2]`) has no out edges to sum a weight on...is that right? if so, do you
happen to know what catches the thrown `FastNoSuchElementException` and
prevents it from bubbling up just kill the whole traversal? (i'm just trying to
