How do you do nested iterators in groovy?

Does groovy support any kind of nested iterator notation?

In the example below, I want to somehow get the projectName value, that came from the outer iterator, into my inner iterator. Is this possible without storing in a variable? In my example I get a runtuime error that "project" is not found

it.myprojects.project.each{
     println("Project name: " + it.projectName)
    it.myroles.role.each{
         Role role = new Role()
             role.setName(project.projectName)//how do I get projectName here without storting it in a variable in the outer loop?
    }
}
