Also, just like with IO, maybe restructuring the code to separate monadic code would help.

The specific monad I am dealing with carries state around inside it.

I could revert to a pure system in many cases by simply passing the state as a parameter but then that defeats the point of the monad and clutters up my function calls.

Also, in other cases, I am using a module that defines its own monads and have no choice but to use them.

I think I would prefer a style of programming where monads are equal citizens to pure function calls. There are various hints that such a style of programming is possible but as I say, I have not found any clear tutorials on it.

It's not much of a tutorial, but Software Tools in Haskell[1][2] apparently uses monads more than some people are comfortable with, including stacks of monad transformers in the later chapters.
