I\'m working on some code that interfaces to a database schema that models a persistent graph. Before I go into the details of my specific question, I thought it might help to provide some motivation.
I have to do an exercise and I´m pretty lost... I need to do an instance for Ord with polynomials. This is my try:
In Haskell, is there a way to restrict a monad M a so that a satisfy a type class constraint? I am translating the probabilistic modeling example from F# to Haskell. However, in Haskell, I omitted su
I understand that in Haskell it\'s important to put the most \'variable\' argument (aka the input object) last in a function definition, to make the function as composable as possible (reference). But
I have a type constructor type SimpleFcn α m = m α -> m α and I want to use it in a class where it will be further parameterized later. Namely,
I have been through various papers/articles/blogs and what not about Monads. People talk about them in various context like category theory (what in world is that?) etc. After going through all this a
I was looking at the Applicative class within Haskell libraries and stumbled across Alternative. What is this class good for? A google search did not reveal anything particularly insightful. And it s

Does anyone know how to get cabal install to exploit parallelism?I\'m compiling with GHC, and while I don\'t know if GHC itself can do parallel builds, surely c开发者_如何学JAVAabal install could run
I\'m going through Write Yourself a Scheme and am struck at the exercise 4 on this page. How do I go about this? I\'ve got this far, but have no idea whatsoever where the readHex is supposed to go, m
