You're totally right. The methods need to be reversed, I messed it
up.
class Messenger
def initialize(stack)
@stack = stack
end
def add(msg)
@stack.append do
@stack.app do
para msg
end
end
end
end
Shoes.app do
fill "#F90"
s = stack
m = Messenger.new(s)
s.button "OK" do
m.add("TEST")
end
end
I'm not completely happy with this. It might be better just to wrap `append` in
instance_eval as well. I just hate messing with scope like that.
