[jira] [Updated] (TINKERPOP-1628) Implement TraversalSelectStep

["Daniel Kuppitz (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TINKERPOP-1628?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Kuppitz updated TINKERPOP-1628:
--------------------------------------
    Description: 
It should be possible to have nested {{select()}} or rather to select dynamic keys.

{noformat}
gremlin> aliases = ["marko":"okram"]
gremlin> g.withSideEffect("a", aliases).V().hasLabel("person").
           values("name").as("n").
           optional(select("a").select(select("n")))
==>okram
==>vadas
==>josh
==>peter
{noformat}

I know there are more steps that could / should allow traversals, but to me {{select()}} seems to be the most important one (perhaps because the workaround is / can be super expensive).
