Thanks for pointing that out. You’re right. As soon as I read your comment I realized what I had done. While I was writing the post I was coding something up in Ruby and started getting my names confused.

A minor note – the built-in type you’re converting to and from isn’t an array, it’s a list too. In fact, its implementation is pretty much identical to your ‘List’ type, except it spells “List a” as “[a]“, “Cons” as “:”, and “Nil” as “[]“.

I’ve been going through the (online) book as well very slowly (i have the book as well, but i find some of the comments in the online version very helpful). Wondering how you found the Graham scan questions?

Apparently the irc channel is very helpful (I have yet to go there), but i’ve been finding http://www.haskell.org/hoogle/ to be quite helpful when I diverge from the questions.

So far that (chapter 3) is the one i’ve gotten the most out of – the exercises seem to be less thought out in in the next couple (i’m only up to ch7, and it’s going very slowly).
