# For example, I want to destroy a frame (window):

  # without Class::DotRef:
    # First you need to have the variable $frame.
    $frame->Destroy ;

  # with Cladd::DotRef:
    # you can do this in any point of the code, since the obj. class is global:
    obj.frame.MyFrameID.destroy ;

# You can use DotRef to get a object too:
  $frame = obj.frame.MyFrameID ;
  # And work in the normal way:
  $frame->Destroy ;
