使用Scala的工作表，需要澄清[关闭](Using Scala's worksheet, clarification needed [closed])

以下代码段编译并运行正常

当作为工作表的一部分使用时，我看到错误

为什么这样好？

The following snippet compiles and runs fine

When using as part of worksheet, i see error

Why is this please?

最满意答案

这可能只是一个错误/缺失的功能。

顺便说一句，您可以像下面的代码一样编写joiner来获得相同的行为，它也将避免工作表问题。

def joiner(strings: List[String], separator: String = " ") = strings.mkString(separator)

It's probably just a bug/missing feature.

By the way, you could write joiner like the following code to get the same behaviour, and it also will avoid the worksheet problem.

def joiner(strings: List[String], separator: String = " ") = strings.mkString(separator)
