What's the __repr__ equivalence in ruby?

Question

The __repr__ function of python is fancy as it is called when print OBJECT is used automatically.

Is there a ruby equivalence for it? I thought it was to_s, but, I had p OBJECT doesn't seem to call the to_s method.

=== Added ===

I got something wrong, p OBJECT seems to call to_s method as follows. I got some hints from my the answers to my other question. - http://stackoverflow.com/questions/2625093/rubys-to-s-method-question-from-axe-book-2nd-edition
