> Support Vertex references in grammar
> ------------------------------------
>
> Key: TINKERPOP-2663
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2663
> Project: TinkerPop
> Issue Type: Improvement
> Components: language
> Affects Versions: 3.5.1
> Reporter: Stephen Mallette
> Assignee: Stephen Mallette
> Priority: Major
>
> With Java (and other variants) you can create an {{Element}} easy enough -
> {{ReferenceVertex}} and the like have easy to use constructors.
> {{gremlin-language}} could be made more consistent with such syntax:
> {code}
> g.addE('knows).from(Vertex(1)).to(Vertex(2))
> {code}
