关于对象与闭包的关系的一个有趣小故事

在一个邮件列表里看到一段很有趣的小故事：
RE: What's so cool about Scheme?

Anton van Straaten 写道

  The venerable master Qc Na was walking with his student, Anton. Hoping to prompt the master into a discussion, Anton said "Master, I have heard that objects are a very good thing - is this true?"  Qc Na looked pityingly at his student and replied, "Foolish pupil - objects are merely a poor man's closures."

  Chastised, Anton took his leave from his master and returned to his cell, intent on studying closures. He carefully read the entire "Lambda: The Ultimate..." series of papers and its cousins, and implemented a small Scheme interpreter with a closure-based object system.  He learned much, and looked forward to informing his master of his progress.

  On his next walk with Qc Na, Anton attempted to impress his master by saying "Master, I have diligently studied the matter, and now understand that objects are truly a poor man's closures." Qc Na responded by hitting Anton with his stick, saying "When will you learn? Closures are a poor man's object." At that moment, Anton became enlightened.

哈哈，Anton用十分风趣的口吻把对象与闭包之争的“宗教性”描写了出来。无论从哪个角度出发都能说得通，所以实在没什么争执的必要……
