ANN: data-or
data-or 1.0.0
The data-or package offers a data type for non-exclusive disjunction. This is helpful for things like a generic merge function on sets/maps which could be union, mutual difference, etc. based on which Or value a function argument returns. Also useful for non-truncating zips (cf. zipOr) and other cases where you sometimes want an Either and sometimes want a pair.
