Subject: Ruby and "old"?

I'm just curious as to whether or not there's an eqivalent to an interesting
capability from Eiffel.  What I'd like to be able to do is something like
the following extremely trivial and self-explanatory example:

def decrement(n)
    n -= 1
    raise "Whoopsie..." if n != (old n) - 1
end
