[nem-en] Macros and extension methods

Hi,
I'm trying to learn a bit about macros. I've coded the following macro:

  macro Example (item)
  {
    <[ ($item).Select (fun (x) { x > 2 }) ]>
  }

and then used it in code:

def ls = System.Collections.Generic.List ();
ls.Add (1);
ls.Add (2);
ls.Add (3);
def t = Example (ls);

but the compiler complains: "there is no member named `Select' in 
System.Collections.Generic.List[int] with type ?", even though I've 
added a reference to System.Query.dll and "using System.Query;" at the 
top of the file. It works completely fine without the macro (I mean, 
writing "ls.Select ...").
Is the macros engine some how not usable along with extension methods?

Thanks in advance
