> Key: GROOVY-10028
> URL: https://issues.apache.org/jira/browse/GROOVY-10028
> Project: Groovy
> Issue Type: Improvement
> Components: groovy-jdk
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Minor
> Fix For: 4.0.0-beta-1
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> Consider the following:
> {code:groovy}
> void test(source) {
> Number[] array = source
> println array.class
> println array
> Collection coll = source
> println coll.class
> println coll
> List list = source
> println list.class
> println list
> Set set = source
> println set.class
> println set
> }
> test(new int[] {1,2,3})
> test(Arrays.asList(1,2,3))
> test(Arrays.stream(1,2,3))
> {code}
> Groovy supports automatic/implicit conversion from array to
> array/collection/list/set. And similarly for list to array or set (a list is
> already a collection/iterable). Can the type conversion logic be extended to
> support {{java.util.stream.Stream}} as a source for array/collection/list/set
> to eliminate the need for ".toArray()", ".toList()", ".toSet()" and
> ".collect(...)" in common situations?
