Description

WARNING: This module is an experiment to see how Alternative may be encoded. The authors are not aware of any generalized applicatives that make use of Alternative. 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 Functor f => AlternativeEmpty f where Source #

The encoding of the empty operation.

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