Here's a workaround - i added an edge to the "modern" graph that had "software"
with no "name" property:
{code}
gremlin> g.V().
......1> hasLabel("person").
......2> out("created").
......3> order().by(coalesce(values('name'),constant('x'))).
......4> choose(has("name"),values('name'),constant('x')).
......5> fold()
==>[lop,lop,lop,ripple,x]
{code}
