    val mapn : ('a -> 'b) -> 'a * 'a * 'a * 'a -> 'b * 'b * 'b * 'b

Like `BatTuple.Tuple4.map` but specialized for tuples with elements of the same type.

`mapn f` is equivalent to `map f f f f`.

    val map1 : ('a -> 'e) -> 'a * 'b * 'c * 'd -> 'e * 'b * 'c * 'd

    val map2 : ('b -> 'e) -> 'a * 'b * 'c * 'd -> 'a * 'e * 'c * 'd

    val uncurry : ('a -> 'b -> 'c -> 'd -> 'e) -> 'a * 'b * 'c * 'd -> 'e

    val enum : 'a enumerable -> 'a BatEnum.t

    val of_enum : 'a BatEnum.t -> 'a enumerable

Raises `Failure` if enum does not contain at least 4 elements.
