             Summary: Path0label pre-binding for match()
                 Key: TINKERPOP-3254
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-3254
             Project: TinkerPop
          Issue Type: Improvement
          Components: gql
    Affects Versions: 4.0.0
            Reporter: Stephen Mallette


 When a traverser's path has a step label matching a pattern variable, the step 
currently throws {{UnsupportedOperationException}}. The intended behavior is to 
use that bound
  element as the pattern seed. See {{GqlMatchStep.checkNoPathLabelOverlap}} for 
the guard and its error message documenting the upgrade path.

{code}
g.V(1).as("a").match("(a)-[:knows]->....")
{code}
