Dear TinkerPop developers!
I was recently faced with the task to create the union of a given list
of (anonymous) traversals, each of which had defined start and end
steps. The intended effect was similar to a "UNION ALL" in SQL. This
turned out to be tricky to achieve in Gremlin. Please find the details,
the workaround, and my proposed solution (having "union" as a traversal
start step) here:

I'm happy to discuss this matter. Thank you for your consideration.
Kind regards,
Martin Häusler
