---------------------------------------
Resolution: Won't Do
> Avoid need to fold() to addAll for sack()
> -----------------------------------------
>
> Key: TINKERPOP-2709
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2709
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.5.2
> Reporter: Stephen Mallette
> Priority: Minor
>
> If you want to maintain a collection of things in a sack you can use
> {{addAll}} to combine lists/maps:
>
> {code:java}
> gremlin>
> g.V(3).valueMap('city').sack(assign).by(fold()).V(4).sack(addAll).by(fold()).sack()
> ==>[[city:[Austin]],v[4]]
> {code}
> It would be nice to be able to do that without having to manually
> {{by(fold())}} and simply assume that if an object is not a collection it is
> meant to go into one by virtual of using {{addAll}}. Or perhaps {{addAll}}
> should be reserved for combining collections and we should have a {{add}}
> operator that will add to a collection. There are multiple ways it could
> probably be done.
