> 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?
Exactly.
It's the same thing as doing just `g.V(2).outE()` - the traverser would
simply die as there are no outgoing edges. Likewise with
`outE().values('weight').sum()`, there simply is no sum, hence the traverser
dies.
