We had to get some order into the template funcs – we have so many now, so we created namespaces. Most template funcs have aliases (collections.Where => where), but we decided to just let lang.NumFmt live without it. All of this will make it easier to test, document etc. – and we can just add more as needed without too much worry. And when we have just wrapped existing Go funcs, we have in many cases kept the exact name (including the Go package), i.e. strings.HasPrefix.
