The Learn You a Haskell tutorial has an example of using a let binder in a list comprehension: calcBmis xs = [bmi | (w, h) <- xs, let bmi = w / h ^ 2, bmi >= 25.0]
In F#, I can use | to group cases when pattern matching. For example, let rec factorial n = match n with
I know that Functor and Applicative should be superclasses of Monad, but aren\'t for historical reasons. However, why isn\'t is possible to declare Monad an instance of Functor? This would have roughl
I\'m starting to understand the power of Haskell and how lazy loading can be exploited in ways such as
Passing in a list such as: [1,2,3,4,5] and get back [ [1,2,3,4,5] , [2,3,4,5] , [3,4,5] , [4,5] , [5] , [] ]
Let testFn be a function that takes two Ints. I am trying to write a function that builds an N x M two-di开发者_如何转开发mensional table (a list of lists) containing all the values of (testFn i j) f
