> Java supports each of the following functional interface assignments for a variadic method like {{java.util.Arrays#asList}}.
> {code:groovy}
> import java.util.function.*
> @groovy.transform.CompileStatic
> void test() {
>     Supplier<List> zero = Arrays::asList
>     Function<Integer, List> one = Arrays::asList
>     BiFunction<Integer, Integer, List> two = Arrays::asList
> }
> {code}
> Note: Groovy compiler only produces error for first incompatible method reference.
