About "Learn You a Haskell ...", is it My imagination or is chapter 11
absurdly long and/or thick? I can (and have) read a 100+ page U.S. Supreme
Court ruling, readily understand it, and be able to explain it in plain
English, with next to zero trouble. I spend every work day reading,
parsing, interpreting, and using, the ISO C++ standard. I *taught* My
undergraduate Physics IV class while simultaneously taking it. Yet, chapter
11 feels as if it goes on and on to the point I easily forget what I read
just a few lines before, rendering comprehension of the same an almost
Sisyphean task. Is it just Me? Am I just tired? Is there an alternative
resource for understanding the concepts that particular chapter presents?
Sincerely,
Frank D. Martinez

You are nearing the end of the book, and it is pulling out some more
advanced concepts on you. I didn't understand applicatives until a bit
later, and you certainly don't need to understand them to code reasonable
haskell. Nonetheless, they exist and are used quite a bit and so it is
worthwhile to present them.
It may help you to pull out ghci and start messing with bits of code as you
read so that you can get a feel for it intuitively.

I had originally encountered problems at this point myself. I lost motivation
because I had just had this feeling that programming with applicatives was just
not going to be fun, and it was beginning to seem like Haskell programming
might involve a lot of this. I put the book down for about 1 year. Somewhere
I came across an article on Monads that changed my mind. I started over and am
now almost done with Chapter 13. This time around things are looking a lot
cooler. I think chapters 11,12, and 13 may lack the motivational information
to keep one going. I can say that the author Miran Lipovaca really does a
great job of explaining this material. I don't think you are going to find a
better source. Absolutely every step of the way is laid out in painstaking
detail. Plus there are constant reminders of material that was just covered
that is relevant to the immediate situation. All I can say is go slow and make
sure you understand every detail before proceeding. Keep at it r
egularly so as not to forget important terms. Go back and reread if
necessary. Have the confidence that it will be worthwhile. The Monad chapters
are little bit more interesting, but you will need to understand the
applicatives first. I learned a new word today, "Sisyphean."

My own experience with Learn You a Haskell was different from Jeff's. I
found the stuff on applicatives difficult, and couldn't see their point
much, so I just kept going with the book without bothering to understand
them fully. Monads I found a lot easier to understand and much easier to
see their point. I don't think you need to understand applicatives before
you understand monads; in fact, I think it's easier the other way round.
And monads seem to be used much more often than applicatives in Haskell. I
eventually got back to applicatives when I was mucking around with Parsec.
In the context of parsing, it was a lot easier to understand how they work
and why they're useful.
