Hello.
I have just read Chapter 5 of this book. I cannot understand one
thing.
Question:
I think `eqlist?' is horrible, because I can easily write `equal?'
without this.
It is very straightforward. See, https://gist.github.com/1652234
Why `eqlist?' is needed?
Thank you.

It is not needed. But once you have it, you can write equal? using it.
But I agree, sometimes it's easier and clearer to write a function from
scratch than to try to reuse some other function.
