Description

import groovy.transform.CompileStatic

@CompileStatic
public class Test4 {
    public static void main(String[] args) {
        new Test4().p();
    }
    
    public String hello = "Hello ";

    public void p() {
        assert ['Hello Jochen', 'Hello Daniel'] == ["Jochen", "Daniel"].stream().map(e -> this.hello + e).toList();
    }
}
