title: What operators should have LINQ query expression support?
body: <p>Of the 51 <a href="http://msdn.microsoft.com/en-us/library/bb397896.aspx" rel="nofollow noreferrer">Standard Query Operators</a> (of which only 42 are actually query operators), only 24 are directly supported by Visual Basic 9 and just 11 by C# 3: <a href="http://msdn.microsoft.com/en-us/library/bb882642.aspx" rel="nofollow noreferrer">Query Expression Syntax for Standard Query Operators</a>.</p>
  
  <p>In many cases, query syntax is arguably more readable than the equivalent method syntax, especially when transparent identifiers are involved. However, that readability breaks down if you have to combine queries and method calls.</p>
  
  <p>So the question: <strong>What query operators, current or hypothetical, would you like to have your language of choice support in query expression syntax?</strong></p>
