For the -opt, -neg and -join operations, multiple-named variables may be listed in the token, for example, {-opt|/|foo,bar,baz}.
对于 -opt、-neg和-join操作,可以在标记中列出多个指定变量。例如,{-opt|/|foo,bar,baz}。
We can see that we can shorten the namespace prefix when referencing a child namespace within the current namespace (the Foo/Bar/hello() call can be shortened to Bar/hello()).
可以看到,在当前名称空间内引用子名称空间时,可以缩短名称空间前缀(Foo/Bar/hello()调用可被缩短为 Bar/hello())。
