[Pharo-dev] I wanted to understand new list

And NewListExample new withNewList; openInWindow. does not work. separatorAfter: item at: index ^ separatorSelector ifNotNil: [ self model perform: 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.
