I am dealing with ByteStrings and at this one place I need to use [Word8] but I have a ByteString. How do I convert a ByteString to [Word8] list?

I tried unpack function from ByteString library but it returned a [Char] list rather than [Word8] list. Do I need to take this step and convert it first to [Char] list and only to [Word8] list? If so, how do I do that.

Please advise the most efficient method!

Thank you!

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
