--------------------------------------
Resolution: Won't Do
at this point we pretty much need to maintain insertion order with {{fold()}}
so {{Set}} won't work here.
> FoldStep should default to using BulkSet for efficiency.

> Key: TINKERPOP-873
> URL: https://issues.apache.org/jira/browse/TINKERPOP-873
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.0.2-incubating
> Reporter: Marko A. Rodriguez
> Assignee: Marko A. Rodriguez
> Priority: Major
> Labels: breaking
>
> This is easy, the problem is that:
> {code}
> GraphTraversal<S,List<E>> fold()
> {code}
> would become:
> {code}
> GraphTraversal<S,Set<E>> fold()
> {code}
> We could make {{BulkSet}} implement List as it does in fact contain all the
> elements inserted, just not in their respective insert order. Does {{List}}
> require that the insert order be preserved? {{UnorderedList}} (is that a
> thing?)
