> Create DGM#subList(IntRange) method
> -----------------------------------
>
>                 Key: GROOVY-11678
>                 URL: https://issues.apache.org/jira/browse/GROOVY-11678
>             Project: Groovy
>          Issue Type: New Feature
>            Reporter: Paul King
>            Assignee: Paul King
>            Priority: Major
>
> We recently added some DGM variants on Lists which take an IntRange. Rather 
> than keep adding such variants, it makes more sense to piggy-back of JDK 
> subList functionality and provide a subList method that takes a range.
> {code:groovy}
> def list = [1, 2, 3, 3, 4, 4, 5, 6, 7]
> assert list.partitionPoint(0..<4) { it <= 20 } == 4 // alt1
> assert list.subList(0..<4).partitionPoint { it <= 20 } == 4 // alt2
> {code}
> It would allow us to offer the second alternative instead of the first, 
> potentially removing the need for one variant.
> Another example:
> {code:groovy}
> def nums = [5, 9, 1, 7, 3, 4, 8, 6, 0, 2]
> nums.sort(0..4)  // alt1
> nums.subList(0..4).sort()  // alt2
> assert nums == [1, 3, 5, 7, 9, 4, 8, 6, 0, 2]
> {code}
> The other mutating methods, e.g. {{shuffle}}, {{unique}}, {{clear}}, could 
> also be used and we don't need more variants.
> It would still make sense to keep some variants, e.g.:
> {code:groovy}
> assert nums.toSorted(0..4) == [1, 3, 5, 7, 9, 4, 8, 6, 0, 2]
> {code}
> Since we sort on the int range but return the whole list.
> It may also make sense to keep variants where we want to offer the same 
> functionality with index selection across more aggregates, e.g. lists and 
> arrays.
