Stephen Mallette closed TINKERPOP-2915.
---------------------------------------
Resolution: Workaround
not sure there is much that can be changed here. providers who need this for
internal purposes could just avoid {{__}} altogether and create their own spawn
mechanism for anonymous traversals. the primary need to plug in a providers
implementation in TinkerPop is in the grammar parser. We already have a
{{Supplier<GraphTraversal<?,?>> createAnonymous}} option that allows them to
plug in that implementation. If we had other places where this was an issue I
think we'd just do something similar to allow it rather than try to make it
work through {{__}}.
