Control.Super.Monad.MonadPlus

Description

WARNING: This module is an experiment to see how MonadPlus may be encoded. The authors are not aware of any generalized monads that make use of MonadPlus. Hence, we do not know if this encoding of it is sufficient. Therefore, the encoding is not in its final form and may change in the future.

Synopsis

Documentation

class AlternativeEmpty m => MonadPlusZero m where Source #

The encoding of the mzero operation.

Return is not a superclass, because the indices or constraints involved in an MonadPlusZero instance may differ from those involved with the Return instance.

WARNING: This module is an experiment to see how MonadPlus may be encoded. The authors are not aware of any generalized applicatives that make use of MonadPlus. Hence, we do not know if this encoding of it is sufficient. Therefore, the encoding is not in its final form and may change in the future.
