title: Array assertion in Spock
body: <p>I have a list of some objects - let's assume companies. Now I want to check if this list contains companies with some names but not taking order into consideration. Currently I'm using such construction:</p>
  
  <p><code>companyList.name.sort() == ["First", "Second"]</code></p>
  
  <p>Is there any operator in Spock or Groovy that allows me to compare arrays without order?</p>
