my_redis.rb

class MyRedis
  def self.conn
    connect unless @conn
    begin
      @conn.ping
    rescue Redis::BaseConnectionError
      raise if @tried
      @tried = true
      connect
      retry
    end
    @conn
  end
  
  def self.connect
    @conn = Redis.new ...whatever...
  end
end

### then you just use it like
MyRedis.conn.call_redis_methods
