In vet, the shadow check is experimental, meaning not on by default.
The new analysis API has no concept of experimental, but you can
easily supply a different checker. By providing a shadow command, we
make it easy for users that want it to run it:
$ go install golang.org/x/tools/go/analysis/passes/shadow/cmd/shadow
$ go vet -vettool $(which shadow) my/project
