Haskell

A good blog post on avoiding space leaks in Haskell showed up on my feed today. First of all I think it provides some useful and important advice for Haskell programmers. I think it touches on some of the same issues that I wrote about recently in a post regarding stacks and laziness. The author starts off stating (correctly) that lazy languages are not the norm, nor particularly popular: Haskell is a purely functional lazy programming language. The world doesn’t have a lot of lazy-by-default PLs. In fact, all mainstream languages have eager evaluation models. ...

The Entropic Thoughts blog has a new post: “Non-Obvious Haskell Idiom: ViewPattern Argument Transform” regarding something I didn’t know existed in Haskell, and it touches upon something I’ve written about before so I’d like to say how they are related, and wonder whether this is the correct solution, I don’t have a better one. So first the new feature in Haskell is a “ViewPattern argument transform”. What is one of those? Well suppose you have a function such as: ...

Cracking post on the Elm discourse by john_s in response to rupert’s question regarding “intensely monadic code”. In his response john_s details some findings from a review of 300k lines of Purescript/Haskell code: In surveying over 300K lines of PureScript / Haskell code in 4 large applications I believe the most genuinely needed monadic binds I ever saw in any properly sized function was 4 and was 1 on average!!!. In other cases, ...
