title: generic Enumeration to Iterable converter
body: <p>HttpServletRequest is using a lot of java.util.Enumeration. I would like to use them in for-each, so i need to convert them into interable. this is not a problem, but I since I have more than one project needing this I need a library to do this. I would rather not make my own - is there any standard library that supports this kind of decoration?</p>
  
  <p>Is there a built-in construct to convert an Enumeration to an Iterable?</p>
