Currying in C#... yes or no ?

curry.cs

dynamic fizzbuzz = new Curry()
    .On<int>()
        .When(x => x % 15 == 0).Do(x => "fizzbuzz")
        .When(x => x % 3 == 0).Do(x => "fizz")
        .When(x => x % 5 == 0).Do(x => "buzz")
        .Do(x=>x)
    .On<IEnumerable<int>>()
        .Do((s, r) => from val in r select s(r))
    .On<string>()
        .When("fizzbuzz").Do(x => "Aha, you found the easter egg!")
    .On<int, int>()
        .When((from, to) => to >= from).Do((s, from, to) => s(IEnumerable<int>.Range(from, to - from)));
 
fizzbuzz(1,100);
fizzbuzz("muahahaha"); // throws exception
fizzbuzz("fizzbuzz"); // returns "Aha, you found the easter egg!"

Ahum... Pattern matching - not currying
