摘自UNIX版本6源代码，大约1975年:

/* You are not expected to understand this. */

<!-- Here it is -->

没有其他评论了。直到今天我都不知道“它”是什么。

// no comments for you
// it was hard to write
// so it should be hard to read

//marco 2007.1.23
//I didn't do it

#ifdef TRACE
#undef TRACE     /* All your trace are belong to us. */
#endif
#define TRACE ....
