好的，在这个函数中它是一个前缀符号,就是一个星号，在键盘中用Shift-8输入。
Well, it's a prefix most of the symbols in this function with just an asterisk, with a * from the keyboard so Shift-8.
这一点已经得到了修正，而且更加便利：lex和yacc的最新版本都允许您在生成代码的符号名称上指定一个前缀。
Conveniently, this has been corrected: modern versions of both lex and yacc allow you to specify a prefix to use on the names of symbols in generated code.
换言之，没有美元符号锚定字符串的结尾，带有匹配前缀（例如 “martin1234-cruft”）的非常长的字符串将生成误判 (false positive)。
In other words, without the dollar sign to anchor the end of the string, a very long string with a matching prefix, such as "martin1234-cruft," would yield a false positive.
