title: Find if any value in a list exists in another list
body: <p>im a newbie in groovy so i have a question, i have two lists, and i want to know if a value that exists in the first list also exists in the second list, and it must return true or false.</p>
  
  <p>I tried to make a short test but it doesn't works... here is what i tried:</p>
  
  <pre><code>// List 1
  def modes = ["custom","not_specified","me2"]
  // List 2
  def modesConf = ["me1", "me2"]
  // Bool
  def test = false
  
  test = modesConf.any { it =~ modes }
  print test
  </code></pre>
  
  <p>but if i change the value of "me2" in the first array to "mex2" it returns true when it must return false</p>
  
  <p>Any idea?</p>
