In my opinion, in Haskell, you don't need coroutines because you have lazy evaluation.

You example below is simply an example of a heterogenous list being read. The simplest way to implement a heterogenous list in Haskell is to use a tuple. Or you could use the HList package.

Lazy evaluation obviates some, but certainly not all uses of coroutines.
