ghc-these

An either-or-both data type

This 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"). ' data These a b = This a | That b | These a b ' Since version 1, this package was split into parts: * <https://hackage.haskell.org/package/semialign semialign> For 'Align' and 'Zip' type-classes. * <https://hackage.haskell.org/package/semialign-indexed semialign-indexed> For 'SemialignWithIndex' class, providing 'ialignWith' and 'izipWith'. * <https://hackage.haskell.org/package/these-lens these-lens> For lens combinators. * <http://hackage.haskell.org/package/monad-chronicle monad-chronicle> For transformers variant of 'These'.
