I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

在angular里使用图标,监听事件的回调函数需要绑定this,使用bind(this)或者匿名函数后,取消监听事件会判断为不是同一个函数,不能取消监听

What does the proposed API look like?

这个功能应该怎么实现

这是一个通用问题，其他的库中也会遇到类似的问题。解法其实很简单，就是把这个 function 存起来，有几种方式：

function 挂到 this 上存起来
function 放到全局，保证引用不变
技术栈中的一些方法可以保持引用，比如 React 中的 useCallback
