title: Can I use Linq's Except() with a lambda expression comparer?
body: <p>I know I can call linq's Except and specify a custom IEqualityComparer, but implementing a new Comparer class for each data type seems like an overkill for this purpose. Can I use a lambda expression to provide the equality function, like when I use Where or other LINQ functions?</p>
  
  <p>If I can't, is there an alternative?</p>
