-----------------------------------------
Summary: withSack() should not be a requirement for the use of
sack()
Key: TINKERPOP-1607
URL: https://issues.apache.org/jira/browse/TINKERPOP-1607
Project: TinkerPop
Issue Type: Improvement
Affects Versions: 3.2.3
Reporter: Daniel Kuppitz
{{withSack()}} initializes the sack value, but also adds the {{SackStrategy}}.
Since we can do {{sack(assign)}} anywhere in the traversal, it's not obvious
that you have to initialize the sack value upfront. However, if you don't do
it, you end up getting NPEs (I think it's because {{SackStrategy}} was not
added).
In short: {{SackStrategy}} should not only be added by {{withSack()}}, but also
whenever you add a {{SackStep}}.
