In Haskell, the Functor typeclass functor is defined as follows (see e.g. Haskell wiki): class Functor (f :: * -> *) where fmap :: (a -> b) -> f a -> f b As far as I understand ...
I want to define a type class for geometric objects that can be intersected together: class Intersect a b c | a b -> c where intersect :: a -> b -> c -- Language extensions: ...
I'm messing around with binary trees, and I'm trying to get a very rough benchmark of a few functions using GHCi. I only want to get the time required to evaluate the test functions; not how long it ...
I'm writing a framework in Haskell where I'd like to use OpenGL to draw lines, shapes... I'm encountering a problem defining the structure of my program. I have for example a Polyline type which holds ...
