title: List without duplicates?
body: <p>I just read <a href="https://stackoverflow.com/questions/268672/is-there-a-no-duplicate-list-implementation-out-there">Is there a no-duplicate List implementation out there?</a> answer about a <code>List</code>, NOT <code>Set</code>, implementation that doesn't allow duplicates. The accepted answer recommended the Collections15 <code>SetUniqueList</code>. Is there some equivalent -- in Guava perhaps? (I searched the docs and couldn't find) -- in other libs or is there some other currently popular solution?</p>
