M. Justin commented on GROOVY-5711:
-----------------------------------
Even if it's not the "minus" method, something like "withoutKeys" or something
would still be useful to me. In my scripts and Spock tests, often I want a
copy of a map but with certain removed. Right now, it's a bit verbose to do
that manually, and this feels like the type of method Groovy would have.
> add a Map.minus(Collection) method to GDK

> Key: GROOVY-5711
> URL: https://issues.apache.org/jira/browse/GROOVY-5711
> Project: Groovy
> Issue Type: Improvement
> Components: groovy-jdk
> Affects Versions: 2.0.2
> Reporter: Rob Fletcher
> Assignee: Jochen Theodorou
> Priority: Minor
>
> Currently we can do Map.minus(Map) but it would probably be useful to be able
> to filter a Map based on its keys. If we had Map.minus(Collection) where the
> Collection parameter represents the set of keys that should be removed this
> kind of filtering would be trivial.
