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:

#!/usr/bin/env python
# coding=utf-8
#
# s3up.py
# 2010-2011, Mike Tigas
# https://mike.tig.as/
#
# Usage:
# s3up filename
#    Uploads the given file to the DEFAULT_BUCKET (see below)
