title: NHibernate HQL Query: Expressions in the Select clause
body: <p>Is there any way to use expressions in the Select clause?</p>
  
  <p>E.g.:</p>
  
  <p>select u.Age/2
  from User u</p>
  
  <p>I'm having this exception right now:</p>
  
  <p>NHibernate.QueryException: ',' expected in SELECT before:/ [select u.Age/2 from Business.Entities.User u]</p>
