Polymorphic kinds are an extension to Haskell's type system, supported by UHC, allowing

data A x y = A (x y)

to be typed (kinded?) as a -> (a -> *) -> *. What are they useful for?

Learning Haskell: How to remove an item from a List in Haskell

Trying to learn Haskell. I am trying to write a simple function to remove a number from a list without using built-in function (delete...I think). For the sake of simplicity, let's assume that the input parameter is an Integer and the list is an Integer list. Here is the code I have, Please tell me… >>> More

I'm trying to use Haskells Data.Heap module, but I'm incapable of even using it with integers. The only heap I've been capable of using is "empty", which does not take any arguments. Later on I'll figure out how to instance for my needs, but for now I'd be glad if I was even able to test it with… >>> More

I've always wondered where did the word "Polymorphism" word come from. I know what is polymorphism and I use it of course, but I just don't understand why this technique called polymorphism.
