像Laravel 的集合类的高阶消息，用起来就很 Nice，例如：

$collect->map(function($item){
       return $item['value'];
});
// 可以写成这样
$collect->map->value;

// 方法调用
$collect->map(function($item){
       return $item->foo();
});
// 可以写成这样
$collect->map->foo();

// ...

I got few migrations each referring a different connection. migrate:fresh, migrate:refresh doesn't handle this scenario since they operate on the default connection or in the specific connection passed via --database param.

Describe the solution you'd like
The simplest solution can be to process only migrations that has th

Hello, I'm so sorry, but I'm really interested in this library, but I don't quite understand from the diagrams what is going on.

Do you think we can work together to improve the documentation? My naivety might help to improve the documentation as I can point out what I don't understand and perhaps make a PR with improved documentation.

In the first instance, I don't understand how this diffe

Thanks for the awesome library!

I think it would be good to expand the audience so lets write all documentation and comments in Russian also. Then in Thai, then in German and Spanish. Then in Hindi-Urdu and Arabic.

P.S. Or just do it one time in English

This is not currently being tested, and as it is a template method, we don't even check it builds correctly.

PSR的RequestInterface没有规定实现exec方法，所以我设计组装一个http客户端无关的request的时候，我肯定不能绑定和客户端强相关的exec方法到Request上，因为每个客户端的异常类型、处理逻辑都不相同。

我设计一个composer组件，在组装请求部分，返回了个psr对象，本意是guzzle或者saber等支持PSR标准的HTTP客户端都可以按psr标准把这个对象代表的请求发送出去，现在Guzzle可以做到（$guzzleClient->send($PSRrequest)）而saber因为把PSR相关的处理逻辑绑定到他自定义的Request上，导致这样的设计没法实施。
