Hello,
I've got a problem, in short my haskell code sucks. While it does work and I do manage to use higher-orderish aspects quite extensively to make my code more concise it still is nowhere abstract, always concrete and thus always with lots of boilerplate.
Oh I have gotten better compared to when I started but on the abstraction slope I'm still stuck.
So fellows, what is the next stop on my road to enlightenment? I really think I need best to start from scratch. I think I'm sufficiently familiar now with most of Haskell's technicalities but how do I climb the ladder of abstraction?
It's actually okay: you come up with abstractions as a result of abstracting things out, :) not the other way round. I'd advise you to read "How To Design Programs". Unrelated to Haskell, it shows a bunch of nice examples of abstraction, including the steps required to get there, with motivation and justifications. The books is aimed at beginners in programming, but don't let that discourage you: it has good ideas to share. Cheers, Artyom Shalkhakov
