> Key: TINKERPOP-3008
> URL: https://issues.apache.org/jira/browse/TINKERPOP-3008
> Project: TinkerPop
> Issue Type: Task
> Components: process
> Affects Versions: 3.7.0
> Reporter: Yang Xia
> Assignee: Yang Xia
> Priority: Major
> Labels: breaking
> Fix For: 3.7.1
>
>
> As proposed on the devlist, updating concat() to accept traversal varags.
> Also to update `concat()` to not special treat `inject()` in parameters and
> use `TraversalUtil.apply` on it as with any other child traversals.
> So the corrected result as inject() behaves by default (The inject() step
> injects the incoming traverser as the first item in the stream by default)
> would be:
> {code:java}
> gremlin> g.inject("a").concat(inject("b"))
> ==>aa{code}
