What happens when this program is built and run?

package main

import "fmt"

func main() {
    if v := 10; v > 5 {
        v++
    }
    fmt.Println(v)
}

It does not compile

Expecting 11: a variable declared in the if init statement exists only inside the if and its else; after the closing brace v is undefined.
Expecting a zero-valued v after the if: there is no outer v at all, so the compiler stops with undefined: v.

How would you change the program so that it prints 11?
Which other statements in Go let you declare a variable for that statement only?
