Module Fn
module Fn: Fn
val (|!) : 'a -> ('a -> 'b) -> 'b
A 'pipe' operator.
val const : 'a -> 'b -> 'a
produces a function that just returns its first argument
val ignore : 'a -> unit
* ignore is the same as Pervasives.ignore. It is useful to have here so
* that code that rebinds ignore can still refer to Fn.ignore.
val non : ('a -> bool) -> 'a -> bool
Negates a function
val forever : (unit -> unit) -> exn
forever f runs f () until it throws an exception and returns the
exception. This function is useful for read_line loops, etc.
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
val compose : ('b -> 'c) -> ('a -> 'b) -> 'a -> 'c
compose f g x is f (g x)
val flip : ('a -> 'b -> 'c) -> 'b -> 'a -> 'c
reverse the order of arguments for a binary function
