parenthesis language的意思|示意

Can these operators be nested in parenthesis and mixed with the other query language operators?

这些操作符会被嵌套在括号中并与其他的查询语言操作符混合在一起吗？

To achieve this goal even further, the grammar of the language was tweaked to allow us to use named parameters without the surrounding parenthesis.

为了更进一步实现这个目标，Groovy的语法做了通融，允许我们使用没有圆括号括起来的命名参数。
