-----------------------------------------

             Summary: Folding in property() step is screwed
                 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: Daniel Kuppitz


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.
