val const : 'a -> _ -> 'a

Produces a function that just returns its first argument.

val ignore : _ -> unit

Negates a boolean function.

val forever : ( unit -> unit ) -> exn

val apply_n_times : n:int -> ( 'a -> 'a ) -> 'a -> 'a

apply_n_times ~n f x is the n-fold application of f to x.

val id : 'a -> 'a

The identity function.

See also: Sys.opaque_identity.

val compose : ( 'b -> 'c ) -> ( 'a -> 'b ) -> 'a -> 'c

compose f g x is f (g x).

val flip : ( 'a -> 'b -> 'c ) -> 'b -> 'a -> 'c

Reverses the order of arguments for a binary function.
