Hi,<div><br></div><div>In a couple of places in my app I found that I was writing in effect a detect: method using PREnumberableVisitor&gt;&gt;do. So I thought I&#39;d add detect: to PREnumberableVisitor which makes the intent of my code much clearer. Would this be useful addition generally? I&#39;ve attached an mcz of the PREnumberableVisitor additions and another of tests to exercise the additions.</div>
