MonadBi (monadbi-0.1)
Note: This repo is currently not being maintained. I may start working on this again if some fresh and promising ideas come up.
This module provides a Class called MonadBi
which acts as a superset of MonadTrans
,
and provides raise
analogous to lift
, i.e. lifts underlying monads into the transformer.
It also provides lower
which is the opposite of lift
, and extracts underlying monads
from monad transformers.
Generally speaking, MonadBi represents the relationship between monads that can be transformed into each other (atleast partially).
Natural instances are provided for many Monad Transformers.
