             Summary: Add the ability to reverse the stream or a collection
                 Key: TINKERPOP-2520
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-2520
             Project: TinkerPop
          Issue Type: New Feature
            Reporter: Kelvin R. Lawrence


I had a Gremlin user ask me yesterday if there was a way to have the results of a `path` step be reversed. Today you cannot do that using `from` and `to` steps as the `from` label must appear before the `to` label in a path. In thinking about this, perhaps adding a `reverse` option to order (on top of `asc`,`desc` and `shuffle`) would be a nice addition to Gremlin. So you could write something like:
{code:java}
g.V().out().out().path().order(local).by(reverse){code}
For this specific user they were union-ing a set of paths in different directions and wanted to normalize them to all be in the same direction when presented as results.
