To solve this, we can push that method call into a closure and make the calls against that closure, instead. The resulting code is shown below.

为了解决此问题，我们可以把该方法调用放入闭包并转而针对该闭包执行调用。

youdao

A method or function can communicate with a closure by passing in arguments.

方法或函数可通过传入参数与闭包通信。

youdao

Because it is a Seq, it has a foreach method that takes a closure as a parameter.

因为它是一个Seq，它具有一个foreach方法，并将一个闭包作为参数。
