Sorry to be a pest, but could you add more complex tests still! :)
```
outE().count().is(0).inV()
both().both().count().is(0).as("a")
```
For the latter, should it be `not(both().both())` ? What are the semantics
in longer chains -- also, what about local children and global children. All
your test cases are basically "the same" in terms of just `out().*`.
