/* This is when a refactoring really pays off.
 *
 * In order to make your code more modular, avoid hard-coding assumptions (or refactor them away).
 * The most fundamental, anti-modular assumption in Object-Oriented software is the concrete type of objects.
 * Any time you write "new MyClass" in your code (or in Ruby MyClass.new) you've hardcoded
 * an assumption about the concrete class of the object you're allocating. These makes it impossible, for example,
 * for someone to later add logging around method invocations of that object, or timeouts, or whatever.
 * 
 * In a very dynamic language like Ruby, open classes and method aliasing mitigate this problem, but
 * they don't solve it. If you manipulate a class to add logging, all instances of that class will have

# Description: Simple demo to showcase Redis PubSub with EventMachine
#
# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
#   the WebSocket protocol implementation in the cramp gem does not work
#   well with Chrome's (newer) WebSocket implementation.
#
# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby
