NewListExample new withNewList; openInWindow.

Should probably be ifNotNil: [ self model perform: self separatorSelector with: item with: index ]

separatorSelector is a valueHolder and not a symbol

but I do not get it because

separatorSelector ^ separatorSelector contents

separatorSelector: anObject separatorSelector contents: anObject

really looks like a valueHolder.

It is a value holder for sure :) I will have a look tomorrow to make the example works :) Ben
