Because it's Pluggable.

You don't make them using 'new', generally; you use one of the 
class-side constructors.

And you can specify what the get-list, get-selection, and 
set-selection selectors are (as well as some others).

So here, the get-list selector is #yourself, and the get-selected 
selector is #size. And when I change the list, I have to send a 
#changed method whose aspect is the same as the selector:

l _ OrderedCollection withAll: #(uno dos tres).
plm _ PluggableListMorph on: l list: #yourself selected: #size 
changeSelected: nil.
plm openInWorld.
l addLast: #cuatro; changed: #yourself.
