    Great Presentation!
    I am watchin git for the second time and coding along through the demo. However,  I am getting an error in the StockAnalyzer type... 

    type StockAnalyzer (lprices, days) =

    let prices =
            |> Seq.map snd
            |> Seq.take days
    static member GetAnalyzers (tickers,days) = 
        |> Seq.map loadPrices
        |> Seq.map (fun prices -> new StockAnalyzer (prices, days))
    member s.Return = 
        let lastPrice = prices |> Seq.nth 0
        let startPrice = prices |> Seq.nth (days - 1)    
        lastPrice / startPrice -1.

    ... the last line is not working ... getting "This value is not a function and cannot be applied" error when mouseover startPrice variable. Any advice for f# newbie? I am running the version of f# with VS  integrated shell.
