Go

I took an initial look at one of Google's newest technologies today - Go, introduced in 2009 - and I liked what I saw. I plan on spending time in the future with this language. It literally took me less than five minutes from the time I first looked at Go to write this version of Euler1:

package main

func euler(size int) int {
    retval := 0
    for i := 1; i < size; i++ {
        if i%3==0 || i%5==0 {
            retval += i
        }
    }
    return retval
}

func main() {
    println(euler(1000))
}

Go's home page opens up to an interactive code editor, complete with samples, which lets you immediately play with the language. Nothing to install - brilliant! To run, just put your code in the online editor and click Compile and Run:
