module T : sig ... end

module C : BaseCollectionM

include BaseCollectionM with type 'a m = T.s -> (T.s * 'a) C.m

include BaseLazyPlus with type 'a m = T.s -> (T.s * 'a) C.m

include BatInterfaces.Monad with type 'a m = T.s -> (T.s * 'a) C.m

type 'a m = T.s -> (T.s * 'a) C.m

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.

val return : 'a -> 'a m

Return a value, that is, put a value in the monad.

val zero : unit -> 'a m

val lplus : 'a m -> 'a m Stdlib.Lazy.t -> 'a m

val null : 'a m -> bool

null x implies that x is zero. If you do not want to or cannot answer whether a given x is zero, then null x should be false.

val difference : ('a -> 'a -> bool) -> 'a m -> 'a m -> 'a m

val unique : ('a -> 'a -> bool) -> 'a m -> 'a m

val maxima : ('a -> 'a -> bool) -> 'a m -> 'a m

val nub : ('a -> 'a -> bool) -> 'a m -> 'a m

val read : T.s m

val write : T.s -> unit m

val cmp_on : ('a -> 'a -> bool) -> (T.s * 'a) -> (T.s * 'a) -> bool

Lift a comparison function to the writer.
