[go-nuts] A question, simple for go team

[T L]

The string struct used internally is

type stringStruct struct {
    str unsafe.Pointer
    len int
}

When following f function is called and s is cleared, 
how do go runtime knows the starting memory address of the old s.str is "a" 
instead of "c"?

var s = "abcdefg"[2:5] // s.str should point at "c".

func f() {
    s = ""
}
