What does the program print?

package main

import "fmt"

func main() {
    s := 0
    for i := 1; i < 5; i++ {
        s += i
    }
    fmt.Println(s)
}

Expecting 15: the condition i < 5 is false once i reaches 5, so the body runs for 1, 2, 3 and 4 only.
Expecting the running sums 1 3 6 10: fmt.Println sits after the loop's closing brace, so it runs once, when the loop is over.
