The lazy monad. Automatically wraps calls lazily and forces as needed.

include BatInterfaces.Monad with type 'a m = 'a Lazy.t
type 'a m = 'a Lazy.t

The type of a monad producing values of type 'a.

val bind : 'a m -> ('a -> 'b m) -> 'b m

Monadic binding.

bind m f executes first m then f, using the result of m.

include Applicative.Applicative with type 'a m := 'a m
include Applicative.Base with type 'a m := 'a m
val return : 'a -> 'a m
val (<*>) : ('a -> 'b) m -> 'a m -> 'b m

val lift4 : ('a -> 'b -> 'c -> 'd -> 'e) -> 'a m -> 'b m -> 'c m -> 'd m -> 'e m
val (<$>) : ('a -> 'b) -> 'a m -> 'b m

Alias for lift1.
