Es geht auch ohne dieses nervige Interface...

[code=java]    public static Function<Integer, Function<Integer, Function>> myTriFunction =

            x -> y -> f -> y == 0 ? 1 : x * (Integer) ((Function<Integer, Function<Integer, Function>>) f).apply(x).apply(y - 1).apply(f);

    public static BiFunction<Integer, Integer, Integer> myBiFunction =

            (x, y) -> (Integer) myTriFunction.apply(x).apply(y).apply(myTriFunction);[/code]

[code=java]        System.out.println(myBiFunction.apply(3, 5));[/code]
