Subject: Does an instance know his own name?

If a class has built checks and raises an exception if it finds 
something wrong, how can I tell which instance had the error?  I know 
there's an object_id, but can I know the name of the objects own 
instance variable?

huey = Nephew.new
duey = Nephew.new
luey = Nephew.new

duey.raise_error_on_purpose_just_for_fun #-> "Nephew 'duey' raised an 
error"

Also, can an instance know his 'path' from the top-level?

class Donald

 def initialize
   @huey = Nephew.new
   @duey = Nephew.new
   @luey = Nephew.new
 end

end

Donald1 = Donald.new
Donald2 = Donald.new

 Donald1.huey.raise_error_on_purpose_just_for_fun
 #-> "Nephew Donald1.huey raised an error"

Thanks,
