Resource Pool in F#

Erik Schulz, who has written a bunch of articles on how to make XNA games with F# has ported the Resource Pool class I wrote about in F#. Cool!

type FPool<'a>(newRoutine, capacity : int) =
    let queue = Queue<'a> capacity

    member this.Count = queue.Count

    member this.New() =
        if queue.Count > 0 then queue.Dequeue() else newRoutine()

    member this.Return(item) =
        queue.Enqueue(item)

I've been toying around with F# recently, it's good to see an example that you can easily compare and contrast with the C# version. Has anyone else tried out F#?
