Re: How can I learn about Object Oriented programming with lua?

Hi Sean Conner, Steve Donovan and Javier Guerra Giraldez,

You are trying to say the same thing.

The koan(?) from Sean Conner is easy and I feel I understand what all of you are trying to say.

When I first saw OO, I felt OO is the one I can do everything only if I can understand it and can freely use it.

But now you say OO is never enough. There is another nicer and better.

I understand what you are trying to say now.

I even feel sorry for you because you wrote too much to me spending your expensive time.

Thank you very much.

Sincerely

Journeyer

Ah, I am reminded of this koan:

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.
