             Summary: Given PathRetractionStrategy, PathProcessorStrategy can be extended to support partial where() inlining.
                 Key: TINKERPOP-1473
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1473
             Project: TinkerPop
          Issue Type: Improvement
          Components: process
    Affects Versions: 3.2.2
            Reporter: Marko A. Rodriguez


{{PathProcessorStrategy}} has a big chunk of code commented out in it that says: "todo: need to be able to drop path labels for this to work."

Given {{PathRetractionStrategy}}, we can now support:

{code}
where(as('a').out().as('b')) => select('a').where(out().as('b'))
{code}

This is useful for OLAP when you can only process the local star graph and thus, if {{where()}} selects arbitrarily from a path, this rewrite will ensure that the {{where()}} starts at a local star graph and not a "reference element" in the path object.

Note that {{PathProcessorStrategy}} already has test cases for this too (commented out). Just uncomment stuff and go!
