I think I am looking at the problem in a wrong way... What I want to do is using higher-order functions with IO (or an IO-based transformer). For example, let's say I want to apply a function to all the keys in a Map. With pure functions, I would do: Map.mapKeys doSomething myMap But let's suppose the function has a signature: doSomething :: a -> IO b Is there an easy way to apply it?
