to avoid silly "return ()" statements like in

when cond $ do monadicComputationWhoseResultIWantToDiscard return ()

(when cond ∘ void) monadicComputationWhoseResultIWantToDiscard or when cond $ () <$ monadicComputationWhoseResultIWantToDiscard

How is that simpler than

when cond monadicComputationWhoseResultIWantToDiscard

which it would be with the suggested new type?

The original poster wanted to make it simpler, others want to let it be safer.
