I like the idea though scope probably shouldn't be reused for this 
purpose. Python uses something similar a __name__ variable which can be 
checked to see if the code is been executed as the main module:

if '__main__' == __name__:
   print "I'm the main module."

However, I would have implemented the example as follows:

  public void AddNewUser( string Name )
  {
    Lock l = Database.tblUsers.Lock();
    Add( Name, l );
    l.Unlock();
  }

  public void AddNewUser( string Name, Lock l )
  {
    Database.tblUsers.Insert( Name, l );
  }

  public void AddUsers( string[] Names )
  {
    Lock l = Database.tblUsers.Lock();
    foreach( string Name in Names )
      AddNewUser( Name, l );
    l.Unlock();
  }

Also, I would love to have __FUNCTION__ and __CLASS__ compile time 
variables in D like there are in PHP. It would simplify logging.

Cheers.
