From Real World Haskell I read It operates as follows: when a seq expression is evaluated, it forces its first argument to be evaluated, then retu ...
I've stumbled over some irritating things. I know that haskell works with weak head normal form (WHNF) and I know what this is. Typing the following c ...
I find it rather difficult to understand how Haskell will evaluate this primes function. Is the primes function get evaluated over and over, or the pr ...
I have to reduce the following lambda-expression into WHNF, but I am not quite sure how to do it: So, how do I do it? Call-By-Name Reduction? Is t ...
I am not able to explain the following behavior: Now when I specify a type for x: Why does the specification of x's type force y to its weak hea ...
In Haskell, is it possible to test if a value has been evaluated to weak head normal form? If a function already exists, I would expect it to have a s ...
I've been playing with some examples from Simon Marlow's book about parallel and concurrent programming in Haskell and stumbled across an interesting ...
The Haskell definition says: An expression is in weak head normal form (WHNF), if it is either: a constructor (eventually applied to argumen ...
I've read lots on weak head normal form and seq. But I'm still have trouble imagining the logic behind Haskell's order of evaluation A common example ...
I have this code: These functions return lists with each element multiplied by 2: In ghci: Why newList_bad function works 200 times slower th ...
What does Weak Head Normal Form (WHNF) mean? What does Head Normal form (HNF) and Normal Form (NF) mean? Real World Haskell states: The familiar ...
