monad-journal is a simple but powerful answer to the logging problem. A lot
of people think that “logging” is IO-related, while it’s not. Everyone must
know MonadWriter
, which is perfect to log things in pure computations. The issue is that you
can’t access those “things” inside the computation itself. monad-journal
exposes a cool typeclass called MonadJournal that enables you to do so.
