Monad transformers as monoid transformers

Theoretical Computer Science, 2010
AbstractThe incremental approach to modular monadic semantics constructs complex monads by using monad transformers to add computational features to a pre-existing monad. A complication of this approach is that the operations associated to the pre-existing monad need to be lifted to the new monad.In a companion paper by Jaskelioff, the lifting problem ...
