W0401: A name shadowing a context processor variable

A shape's field or a local its markup declares has the name of a context processor variable. As in Go, the nearer name wins: the template reads the field, not the variable. That is how a caller passes a value of its own, so it works; the warning says the variable isn't what is read there. Reported by vuka vet.

Wrong

<script lang="go">
type Badge struct {
	user string // the variable user is the signed-in user
}
</script>

<b>{user}</b>

Right

<script lang="go">
type Badge struct {
	label string
}
</script>

<b>{label} {user.Name}</b>
