Is there an easy way to get neighbours of a vertex without "mapreduceneighbourhood()"?

Only other option is, to explicitly gather() the IN and/or OUT edges, and build your customized neighbour set in apply().
I think it is the easiest way to get neighbours you want. It also depends on your definition of neighbourhood.
