I do not know much about Haskell, but from what I have read about the mutability of computations (e.g: functions returning functions, complex monads and functions, etc.) it seems like you can do a lot of meta-programming, even at runtime.

How can Haskell, if everything like functions and monads are so complex, compile to machine code and retain all this?

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).

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.
