Review Comment:
do we need to override `toString()` for some steps?
> Add List Manipulation Steps to Gremlin
> --------------------------------------
>
> Key: TINKERPOP-2978
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2978
> Project: TinkerPop
> Issue Type: Improvement
> Components: language
> Reporter: Cole Greer
> Priority: Major
>
> Today Gremlin requires that users fall back to closures to handle many common
> list manipulation options that users want to do on data in the graph. This
> is a problem for many users as many of the providers prevent the use of
> closures due to the security risks so for these users there is no way to
> manipulate lists directly.
> A full list of proposed functions and semantics is detailed here:
> https://github.com/apache/tinkerpop/blob/3.7.0/docs/src/dev/future/proposal-3-remove-closures.asciidoc
