cmd/vet: complains about captured range var that's actually a field name

go version devel +4df6dcb Wed Jul 22 16:12:06 2015 -0400 linux/amd64

Vet complains that "v" is captured by this loop; it isn't:

package main

import "fmt"

func main() {
    list := []int{1, 2, 3}
    type s struct {
        v int
    }
    c := make(chan s)
    for v := range list {
        go func(vv int) {
            c <- s{v: vv} // vet complains that v is captured here
        }(v)
    }
    for range list {
        fmt.Println(<-c)
    }
}

Output:

% go run main.go      
{2}
{0}
{1}
% go tool vet main.go
main.go:13: range variable v captured by func literal
