Javascript: The Good Parts is a great book. Often I find myself reading passages like the following from the perspective of a language designer:

undefined and NaN are not constants. They are global variables, and you can change their values. This should not be possible, and yet it is. Don't do it.

Takeaways:

  1. Don't change the value of undefined in my Javascript code.
  2. When designing a language, make its equivalent of undefined immutable.

A different more subtle example would be "for in shouldn't enumerate over prototype properties".

I want a book at talks about these issues of language design outside of the context of a particular language.

If you were trying to design the "perfect" OO language, what books would you read for guidance?
