[maintain] [Publish]

This package is deprecated. It simply re-exports semialign (and adds a lens constraint).

This package provided SemialignWithIndex with two members

class (FunctorWithIndex i f, Semialign f) => SemialignWithIndex i f | f -> i where
    ialignWith :: (i -> These a b -> c) -> f a -> f b -> f c
class (SemialignWithIndex i f, Zip f) => ZipWithIndex i f | f -> i where
    izipWith   :: (i -> a -> b -> c)    -> f a -> f b -> f c
