I still have one question though. Given the part of your answer I
quoted above, why does the “pass” control structure trigger handlers
along the behavior chain rather than skipping over them and going to
the next object in the ownership chain?
Because it is helpful for it to do so.
Either 'pass' could act as you say and skip the entire behavior chain;
or it could do as it currently does and pass to the next script in the
list of things which might want to process the message.
Given the utility of pass in the exisiting message path, it seemed
sensible that it should do the 'similar' thing in the behavior chain. As
currently implemented, it means that you can get a whole list of things
to 'do something' on a particular event; should each one pass (just as
you can with the 'normal' message path).
Warmest Regards,
Mark.
