attr_chain is for when you're building up a
DSL in which you'd like to have attributes
that can be chained together when they're being set.
Its simple and small, you probably aren't interested, I kept on using this pattern and wanted to abstract it away from my other code.
require 'attr_chain' class Chainsaw include AttributeChain attr_chain :start, :cut end >> c = Chainsaw.new >> c.start => nil >> c.start(:now).cut(:hippy) >> c.start => :now >> c.cut => :hippy
