      Description

      I'm trying to use bindings in a traversal strategy like:

          graph = Graph()
          g = graph.traversal().withRemote(DriverRemoteConnection('ws://localhost:8182/gremlin', 'g'))
          g = g.withStrategies(
              SubgraphStrategy(vertices=__.has('foo', ('b', 5)))
          )

      This works unless there is a use of lambda in the traversal:

          g.V().toList() # will work
      
          g.V().filter(lambda: "true").toList() # this will not

      Here is the full TB on the server:

      I've tried also to use python lambdas but it gets worse, I get the
      error:
