A (Nicer) Redis Client for EventMachine

Redis is my favourite key/value store; it’s flexible, easy to set up and insanely fast. [EventMachine][] is a popular Ruby library for doing asynchronous I/O using an event loop. Bindings already [exist][em-redis] for accessing a Redis server using EM’s async-I/O (courtesy of Jonathan Broad), but unfortunately the resulting code has to use [Continuation-Passing Style][cps] via Ruby blocks. A very basic example of what that looks like follows:
