What does the program print?

package main

import "fmt"

func main() {
    var b uint8 = 255
    b++
    fmt.Println(b)
}

Expecting 256: a uint8 holds only 0 to 255 and b++ keeps the type, so 255 + 1 wraps around to 0.
Expecting a compile error: the compiler rejects only a constant that overflows; b++ changes a variable at run time, where the value wraps silently.
