[jira] [Commented] (TINKERPOP-2112) Folding in property() step is
not being optimally performed
[ https://issues.apache.org/jira/browse/TINKERPOP-2112?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17326970#comment-17326970 ]
Daniel C. Weber commented on TINKERPOP-2112:
--------------------------------------------
Currently evaluating Neptune, and this still seems to be a thing in the latest engine (1.0.4.1).

> Key: TINKERPOP-2112
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2112
> Project: TinkerPop
> Issue Type: Bug
> Components: process
> Affects Versions: 3.3.4
> Reporter: Daniel Kuppitz
> Assignee: Stephen Mallette
> Priority: Major
> Fix For: 3.3.7, 3.4.2
>
>
> Somehow we mess up the folding in {{property()}} step when it's used with tokens. I think there's just a missing {{if}} branch, but needs further investigation.
