libghc-neither-dev: version of Either with good monad/applicative instances: This package provides a library for the Haskell programming language.
See http://www.haskell.org/ for more information on Haskell.
.
The standard Either datatype suffers from a lack of monad and
applicative instances. To make matters worse, the mtl and transformers
packages provide orphan instances which conflict with each other, as
well as defining a transformer version which has an usually unnecessary
superclass constraint.
.
Besides these annoyances, there is another issue: there exist two
reasonable definitions of the Applicative instance for Either: one
that holds onto only the first Left value, or one that appends all Left
values together via a Monoid instance. The former is compatible with the
monad instance, while the latter is not.
.
This package defines three datatypes, some helpers functions and
instances. The data types are AEither, MEither and MEitherT. AEither
provides an Applicative instance which appends Left values, MEither
provides the monadic definition, and MEitherT is a monad transformer.

libghc-neither-doc: version of Either with good monad/applicative instances; documentation: This package provides the documentation for a library for the Haskell
programming language.
