We are extremely happy to announce the control-monad-failure and

control-monad-failure provides a basic notion of failure which does not

It is just a version of the MonadError class without the annoying bits.
In my own opinion, the reason why we use the concept of a monoid or a
monad is in order to build libraries around the concepts.
For example, the do construct could have been designed just for
doing IO, but because it works for *any* monad you can also use the
same syntax sugar to
