class RedisException < Exception
  attr_accessor :original_exception
end
class Redis
  class Client
    def call(*args)
      begin
      process(args) do
        read
      end   
      rescue Exception=>e
        err = RedisException.new(e.to_s)
        err.original_exception = e
        raise err
      end    
    end      
  end
