Ned:

As usual I learn a lot from you.
But my answer remains still.
This time I know what you are saying, but, what if you have a
PluggableListMorph  embebed in other Morph and wish add a new member to your
previous ?

How you get list if you don't have
List
^list 

Thot is what I'm asking.

Cheers.
