Oh.  Yeah, sorry.  The return value of onAnswer: is the handler, not  
self as I had thought.  That was sloppy of me - if you're  
initializing an object as you create it like that, the best practice  
is to end things with a cascade to #yourself, like this:

comp1 =: Comp1 new
                         onAnswer: [:val | self selected: val];
                         yourself.
