Is there a way to have multiple actions take place as the result of a
single rule firing?  For example:

define rule foo_bar is
on append to dog
where tail = "wagging"
do instead [ append cat (tail = "swishing") append trace (rule_fired =
"foo_bar") ] 

What I'm really after is a way to trace the process of backward
chaining.  Any suggestions?
