-------------------------------------
Description:
Users are unable to use previously fetched components of a traversal and supply
them as IDs within a mid-traversal `V()` lookup.

{{{}g.inject([['twitterPostId': 'tay','like': 'true','retweet':
'false'],['twitterPostId': 'fay','like': 'true','retweet': 'false'
]]){}}}{{{}.unfold(){}}}
{{{}
.V(select('twitterPostId')).{}}}{{{}fold(){}}}{{{}.coalesce({}}}}.{{{}unfold(),{}}}{{{}addV().property(t.id,
select('twitterPostId').unfold()){}}}
No error is returned in this case. The query returns zero results.
This can be repeated using the air routes dataset{{{}:{}}}
{{g.inject(['1','2','3']).as('a').V(select('a'))}}
Returns 0 results
{{g.V(['1','2','3'])}}
Returns:
{{[v[1], v[2], v[3]]}}
