When in ruby using Pannonica (a component based framework):

 class ArcChallenge < Pan::Task 
 def go 
 msg = call Input.new 
 call ClickHere.new 
 call YouSaid.new(msg) 
 end 
 end
 class Input < Pan::Component 
 def render_on(html) 
 html.form { 
 html.input 
 html.submit {|val| answer(val)} 
 } 
 end 
 end
 class ClickHere < Pan::Component 
 def render_on(html) 
 html.link("Click here") { answer } 
 end 
 end
 class YouSaid < Pan::Component 
 def initialize(msg) 
 @msg = msg 
 end 
 def render_on(html) 
 html.lit("you said: #{@msg}") 
 end 
 end

It is worth noting the use of the seaside-like continuation based task construct.

Though not as tight as mr. Grahams code it does not lack in clarity IMHO.
