nested properties?

[Alex Rice]

How can one find the stack of the object that started a message? I'm 
trying to do something like this

on someMessage
   get the stack of the target
   -- do stuff with it
end someMessage

I have looked at using "owner" and "mouseStack" properties to figure 
this out, but neither seems really what I want. owner could get tricky 
with groups, and "mouseStack" depends on the UI which doesn't seem 
right, if I ever want to turn this into a web app or something.
