Notes on Haskell is a personal blog at notes-on-haskell.blogspot.com about programming. Since 2007, 9 different Hacker News readers have linked it 11 times, most often “What's Wrong with the For Loop”. The last post was in 2010, but the archive is still widely read.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
Linked for a post on why Haskell has no for loop, which argues that lazy evaluation makes parameters behave like closures. Commenters cite it when discussing thunks and iterators.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
I know I am repeating a previous comment but the author correctly explains it here http://notes-on-haskell.blogspot.com/2007/02/whats-wrong-wit... In Haskell all parameters are lazy by default, which effectively turns every parameter into a closure. for e.g., consider the code boost x = map ( x) [1..10] total = sum (boost 2) On invocation of the sum function, the (boost 2) is not necessarily evaluated. Instead a ref…

HN discussionI'm not the author, and I think this was kind of a cop out, but: http://notes-on-haskell.blogspot.com/2007/02/whats-wrong-wit... "A few people have commented that none of the examples use closures, but in Haskell closures are used not only to represent functions but also unevaluated values (i.e., thunks). For example, in the simple expression total = sum array the variable array is free and refers to some value, pos…

HN discussionI also had a reaction when I started using Ruby and being introduced to functional programming concepts. I read blog posts http://notes-on-haskell.blogspot.com/2007/02/whats-wrong-wit... about people saying you don't really need for loops. I thought...well, how do you get anything done ? Ends up that most things you care about can be done with iterators like each , map , and inject (like a fold). On occasion, you'll…
