title: Quick IComparer?
body: <p>Before I go reinventing the wheel, is there some framework way of creating an <code>IComparer&lt;T&gt;</code> from a <code>Func&lt;T,T,int&gt;</code>?</p>
  
  <p>EDIT</p>
  
  <p>IIRC (it's been a while) Java supports anonymous interface implementations. Does such a construct exist in C#, or are delegates considered a complete alternative?</p>
