= Deferrable

Deferrable provides a simple way to defer execution of a block without starting another
process or thread.

== Usage:

  class Foo
    include Deferrable
    
    def bar(opts = {})
      deferred do
        # do something later
      end

      now_and_later do
        # do something now and when deferred blocks are executed
        # this could be useful for cache invalidations... yum
      end
    end
    
    def later
      complete_deferred # executes all deferred blocks in order
    end

    def nevermind
      clear_deferred # don't execute the deferred blocks after all
    end
  end

== Install:

  sudo gem install deferrable -s http://gemcutter.org
