--  eg. myzip [’a’, ’b’, ’c’] [1, 2, 3, 4] -> [(’a’, 1), (’b’, 2), (’c’, 3)]
myzip :: Ord a => [a] -> [a] -> [(a,a)]
myzip list1 list2 = [(x,y) |  [x, _] <-list1, [y,_] <-list2 ]

I get this error message:

 Occurs check: cannot construct the infinite type: a = [a]
    When generalising the type(s) for `myzip'
Failed, modules loaded: none.

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
