title: How to convert Func<T, bool> to Predicate<T>?
body: <p>Yes I've seen <a href="https://stackoverflow.com/questions/665494/c-why-funct-bool-instead-of-predicatet">this</a> but I couldn't find the answer to my specific question.</p>
  
  <p>Given a lambda <strong>testLambda</strong> that takes T and returns a boolean (I can make it either Predicate or Func that's up to me)</p>
  
  <p>I need to be able to use both List.FindIndex(testLambda) (takes a Predicate) and List.Where(testLambda) (takes a Func).  </p>
  
  <p>Any ideas how to do both?</p>
