---------------------------------------------
This is definitely something of interest
Would be great if you can provide a patch.
> [Collection|List]Utils.[intersection|union] should accept vararg parameters

> Key: COLLECTIONS-517
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-517
> Project: Commons Collections
> Issue Type: Improvement
> Components: Collection, List
> Affects Versions: 4.0
> Reporter: Hollis Waite
> Priority: Minor
>
> Would be convenient if intersection/union methods accepted arbitrary number
> of arguments. Two-arg methods could be retained in order to avoid compiler
> warnings
> (https://issues.apache.org/jira/browse/COLLECTIONS-481?focusedCommentId=13762173&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13762173).
> Alternatively, method could be overloaded to accept a single Iterable of
> Lists/Sets. I could create a patch for this if it's deemed worthwhile.
