Hi @sundb . I tried the `__builtin_ctzll ` and updated my test file. It has almost same time cost with De Bruijn method. And they are both faster than the...

Hi, @sundb. This PR indeed bring no performance improvement, but it can simplify the code and improve readability without compromising performance.

@sundb I understand what you mean. So I write a comaprison test by extracting the `hllDenseRegHisto()` [here](https://gist.github.com/panzhongxian/c7dd59bdafb42435c9701df6c90813fc). I built the simplified and not simplified hllDenseRegHisto() function by whether defining `SIMPLIFIED`....

@CapitaineNemo 我看你应是说的微信客服账号对吧？我看API好像有些类似，但是没有实际使用。 你可以试试，然后反馈一下有什么问题哈。 看上去机器人接收消息的协议和其他接收消息的协议是不同的，我们可以做一个兼容。让一个框架，来匹配两个种协议，用户可以在创建基础的Server的时候自行选择，而无需用户了解，只需要进行消息处理即可。 机器人协议：https://developer.work.weixin.qq.com/document/path/95280 客服接收消息协议：https://developer.work.weixin.qq.com/document/path/94670 公众号接收消息协议：https://developers.weixin.qq.com/doc/offiaccount/Getting_Started/Getting_Started_Guide.html

@CapitaineNemo https://developer.work.weixin.qq.com/document/path/90238 我刚才试了一下，可以创建“应用”，也可以实现接收消息和回复消息的功能。但是无法被邀请到群中 但是他的协议跟机器人的不同，我打算另外开一个仓库，来适配企业微信应用的回复消息。 另外的一点不同是，应用这里需要填上企业的ID
