Avoid the use of complicated punctuation marks such as parentheses and hyphen s.

避免使用括号、连字符此类复杂标点。

Notice that each of our regexes defines two capture groups , connoted by parentheses .

注意每一个正则表达式都定义了两个捕捉组，由括号表示。

Figure 1 shows an example from vimclojure , where paired parentheses are matched by color .

figure1是一个vimclojure的例子，匹配的括号是以不同颜色表示的。

If they couldn 't spot the analytical flaws , they might have done something about the stylistic ones that range from curious analogies to long phrases in parentheses .

如果他们不能看到这些分析的瑕疵，他们可能已经做了一些从奇怪的类推法到括号内的冗长的叙述风格的事情。

For example , a regular expression inherently cannot find matched pairs of parentheses , because it is not recursive , but a peg can .

例如，一个正则表达式本身是无法匹配嵌套的括号对，因为正则表达式不是递归的，但是peg却能做到这点。
