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
