An F# HelloWorld Style Crawler / Scraper (if you may)#
I wrote/scavenge this while Amanda Laucher's F# talk yesterday. It's a beauty, this terse F# syntactically & semantically. Having worked with scheme, experimenting with F# comes naturally however James Iry during a 1-1 discussions begs to differ that they are QUITE different. I have yet to independently verify the merit of this claim.

open System.IO
open System.Net            
            
let GetUrl(url:string) =

    let req = WebRequest.Create(url)

    // Get the response, synchronously
    let rsp = req.GetResponse()

    // Grab the response stream and a reader. Clean up when we're done
    use stream = rsp.GetResponseStream()
    use reader = new StreamReader(stream)

    // Synchronous read-to-end, returning the result
    reader.ReadToEnd()

let result = GetUrl("http://www.google.com")
printfn "%s" result
