this is mixed inside the `makeProperty` template itself, not where you
instantiated it. i.e. when compiler sees mixin, it not postponing it.
so what you actually got is `makeProperty` template with `%s`
substituted with `name`, and only then `makeProperty` is mixed at the
place of it's instatiation.
