> Key: GROOVY-12036
> URL: https://issues.apache.org/jira/browse/GROOVY-12036
> Project: Groovy
> Issue Type: Improvement
> Reporter: Paul King
> Assignee: Paul King
> Priority: Major
> Fix For: 6.0.0-alpha-2
>
>
> Cache Collectors.toList() and Collectors.toSet() as static singletons in
> StreamGroovyMethods and ParallelCollectionExtensions, eliminating per-call
> collector allocation in 9 GDK call sites.
> A benefit in Eclipse Collections as noted here:
> https://donraab.medium.com/counting-and-collecting-collectors-d69b7c9aaca0
> Groovy is not a collections library but this is a very minor improvement with
> no downside.
