The weblog without a name

I attended the first session of the novalang sessions on Real World Haskell. So far, I haven’t picked up too much, but we’ve only gone through the first two chapters. It looks like a pretty good group, with a lot of smart folks attending.

The group had a mixture of people using both the physical book and the online version, so there was some confusion when someone would refer to something by page number. It might cut down on some confusion if the HTML had anchor links to the pages in the book.

I was surprised by Exercise 1 at the bottom of chapter 2. It had not occurred to me that last would have to return some element from within [a]. If it returned something else, like 42, then the type checker would catch this and make the signature something more specific like [a]->Int instead.

(It would also be nice if the online version included links to the exercises.)
