What does the program print?

package main

import "fmt"

func check() bool {
    fmt.Print("check ")
    return true
}

func main() {
    fmt.Println(false && check())
}

false

Expecting check false: && stops as soon as its left side is false, so check() is never called and prints nothing.
Expecting true because check() returns true: && is true only when both sides are, and the left side is already false.
