[Rails] Deep Copy Method?

[Thomas Counsell]

Have you got a / can you help with a generic method for doing a deep 
copy of a set of Rails objects?

I see there is a clone method for individual objects.

I can also see it would be pretty easy to implement a method that 
copies down a tree.

The tricky bit is how to deep copy where objects within the tree 
reference each other?

Thanks for any tips.

Tom
