软件包：libghc-these-dev（1.1.1.1-2） [debports]
either-or-both data type
Package provides a data type `These a b' which can hold a value of either type or values of each type. This is usually thought of as an "inclusive or" type (contrasting `Either a b' as "exclusive or") or as an "outer join" type (contrasting `(a, b)' as "inner join").
The major use case of this is provided by the Align class, representing a generalized notion of "zipping with padding" that combines structures without truncating to the size of the smaller input.
Also included is ChronicleT, a monad transformer based on the Monad instance for `These a', along with the usual monad transformer bells and whistles.
This package provides a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
