Fastest Haskell library sort implementation

I am implementing an application in Haskell and, for sorting, I use the library function Data.List.sort. However, I was wondering whether this is the fastest sort implementation in the Haskell standard library (perhaps lists are not the best choice for efficient sorting).

Why would I use Control.Exception in Haskell?

I’m trying to really master Haskell error handling, and I’ve gotten to the point where I don’t understand why I would use Control.Exception instead of Control.Monad.Error.

does haskell have dependent types?

I know Haskell already has the ability to parametrise a type over another type (similar to template programming in C++), but I’m wondering whether Haskell can also parametrise a type over values – whether it supports dependent types. With dependent types, you can have a type that’s parametrised over integers, for example vectors of size n, matrices of size n×m, etc.

Applying Denotational Semantics to design of Programs

I’ve read a bit on denotational semantics (DS) and I’m very intrigued about the process of designing computer programs where types and functions have strong and clear mappings to mathematics.

What monad is the opposite of the error monad in haskell

In the error monad, the first failure halts any execution further just carrying the fault through any following binds.

Why (or why not) are existential types considered bad practice in functional programming?

What are some techniques I might use to consistently refactor code removing the reliance on existential types? Typically these are used to disqualify undesired constructions of your type as well as to allow consumption with a minimal of knowledge about the given type (or so is my understanding).

How to improve efficiency with functional programming?

I’ve recently been going through the Learn You a Haskell for Great Good guide and as practice I wanted to solve Project Euler Problem 5 with it, which specifies:

Better to use error monad with validation in your monadic functions, or implement your own monad with validation directly in your bind?

I’m wondering what’s better design wise for usability/maintainability, and what’s better as far as fitting with the community.
