> Groovy 3 and 4 added some {{Stream}} extension methods like {{plus}}, {{toList}} and {{toArray}}.  And some default type conversions like {{String[] array = stream;}}.  This could be taken further by having spread-dot and subscript support:
> {code:groovy}
> stream*.thing // --> stream.map(it -> it.thing).toList()
> stream[1] // --> stream.skip(1).findFirst().orElse(null)
> stream[1..10] // --> stream.skip(1).limit(10-1).toList()
> // consider negative indexes and reverse ranges
> {code}
> Also, {{forEachPair}} and {{zip}} extension methods would be useful for processing corresponding streams.
