question on instance variable access

[surfunbear]

I came accross a problem which made me wonder. Sort of about dotting
into a variable.
I could find the answer in my ruby book. How would I do the access at
the end here.
I know I could probably use accessors, but is that the only way to do
it ?


class A

def initialize
@num = 3
end

end


class B

def initialize
@friend = A.new
end


myobj = B.new

# syntax here ? Is this allowed, is it done another way ?
x = myobj.@friend.@num

Yes. In Ruby all instance variables are private.

The code would look like:
myobj.instance_variable_get@friend).instance_variable_get@num)
