> Consider the following:
> {code:groovy}
> import java.util.function.*
> @groovy.transform.TypeChecked
> void test() {
>   Consumer c0 = { print it } // error
>   Consumer c1 = { x -> } // all good
>   Supplier s0 = { -> "" } // all good
>   Supplier s1 = { "" } // all good
> }
> {code}
> The implicit parameter closure literal (no arrow) should match for 0 or 1 parameter method targets.
