> The traversal:
> {code}
> g.V().out().id().count()
> {code}
> Requires a message pass from {{out()}}. We shouldn't do this. Instead, if we wrap the pre-barrier stage into a {{local()}}, we have:
> {code}
> g.V().local(out().id()).count()
> {code}
> ...which doesn't require a message pass and has the same semantics. This will help open up numerous OLAP type traversals to single-pass/non-caching scans.
