(synopsis "Either-or-both data type")
(description
"This package provides a data type @code{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 @code{Either a b} as
\"exclusive or\") or as an \"outer join\" type (contrasting @code{(a, b)}
as \"inner join\").
@code{data These a b = This a | That b | These a b}
Since version 1, this package was split into parts:
@itemize
@item
https://hackage.haskell.org/package/semialign For @code{Align} and
@code{Zip} type-classes.
@item
https://hackage.haskell.org/package/semialign-indexed For
@code{SemialignWithIndex} class, providing @code{ialignWith} and
@code{izipWith}
@item
https://hackage.haskell.org/package/these-lens For lens combinators.
@item
http://hackage.haskell.org/package/monad-chronicle For transformers
variant of @code{These}.
