Much thanks to you Kevin (for your help with the callbacks as well),
and Alexander for clearing this up for me!
I must admit I missed the explanation in the Rules page.
Cheers Guys!

To chime in a little bit... because instance variables such as
@stack are defined on self, they will no longer be visible.
However, you can work around this by copying @stack to a local
variable, which will then be visible within your block.
e.g.
st = @stack
@stack.app do
st.append do
para msg
end
end

Hi Jae!
Methods named "app" will change the value of self! Check out:

I'm not quite sure what you're doing here, but do you really need the
@stack.app block?
