----------------------------------------
Component/s: process
> no-arg select dynamic keys
> --------------------------
>
> Key: TINKERPOP3-649
> URL: https://issues.apache.org/jira/browse/TINKERPOP3-649
> Project: TinkerPop 3
> Issue Type: Improvement
> Components: process
> Reporter: Matt Frantz
>
> The currently implementation of the no-arg {{select}} form determines the set
> of labels via static analysis with {{TraversalHelper.getLabelsUpTo}}.
> Instead, it should examine the {{Path}} and create a {{Map}} with keys for
> all labeled steps.
> Compare the current behavior of a 3-arg select on the modern graph:
> {noformat}
> gremlin> g.V().choose{it -> it.id()%3}
> .option(0, __.as('x'))
> .option(1, __.as('y'))
> .option(2, __.as('z'))
> .select('x', 'y', 'z')
> ==>[y:v[1]]
> ==>[z:v[2]]
> ==>[x:v[3]]
> ==>[y:v[4]]
> ==>[z:v[5]]
> ==>[x:v[6]]
> {noformat}
> The expected behavior of {{select()}} in place of {{select('x', 'y', 'z')}}
> would be the same.
