module R:Kwapp.Valid.Number(Kwapp.Valid.Real)
val any : Kwapp.Valid.t optionany considers valid any string that is an integer.val whilst : (N.t -> bool) -> string -> boolwhilst f: combinator for writing predicates on integer switch arguments.
Converts the function f into a function that takes a string.
