> VertexPrograms should declare their {{TraverserRequirement}} which can then be propagated by the {{program()}} step. Most VPs (at least the ones I have written so far) rely on (labeled) path information and thus will fail if the actual traversal doesn't use any other steps with the same traverser requirements. I keep running into this issue whenever I write a new VP.
