[jira] [Comment Edited] (GROOVY-5711) add a Map.minus(Collection) method to GDK

------------------------------------------------------------

Even if it's not the "minus" method, a "withoutKeys" (or similar, better named method) would still be useful to me.  In my scripts and Spock tests, often I want a copy of a map but with entries corresponding to certain keys removed. Right now, it's a bit verbose to do that manually, and this feels like the type of method Groovy would have.

> 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.
