I figured that an append would be treated as a set since I'm adding to
the list.  But what you say makes sense, although I can't say I'm
happy with the behaviour.  Is there any way I can get the append to
fire a set?  I'm thinking of properties from my C# background where i
believe that manipulation such this would be considered a set.
