I guess it would look something like this:
{{__.inject(vertices).as("x").addV("x")}}
It does seem kind of a stretch to do this in a traversal, but it will
enable:
1. Inserting vertices in bulk (see TINKERPOP3-701)
2. {{EventStrategy}} and Validation strategies, which can't work with
{{Graph.addVertex()}}
Maybe you can think of a better way to make those work.
