[jira] [Created] (GROOVY-9813) Improve support for matching functional interface to variadic method reference

Eric Milles created GROOVY-9813:
-----------------------------------

             Summary: Improve support for matching functional interface to variadic method reference
                 Key: GROOVY-9813
                 URL: https://issues.apache.org/jira/browse/GROOVY-9813
             Project: Groovy
          Issue Type: Bug
            Reporter: Eric Milles


Java supports each of the following functional interface assignments for a variadic method like {{java.util.Arrays#asList}}.  Groovy 3 does not yet implement the first case.

{code:groovy}
import java.util.function.*
@groovy.transform.TypeChecked
void test() {
    Supplier<List> zero = Arrays::asList
    Function<Integer, List> one = Arrays::asList
    BiFunction<Integer, Integer, List> two = Arrays::asList
}
{code}
