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.
