How much time do you spend instead on unit tests? Is it comparable? The idea with a Haskell (or more powerful) type system is to reduce the amount of unit tests you need to write (because the compiler enforces certain rules). It's all trade offs, but personally, I know I make mistakes, and I know I won't remember to check for all possible type errors in my unit checks. So I like that the compiler does it for me.
