Looks like a very verbose syntax. However, it's the cleanest suggestion
so far, IMHO. It might be perfectly reasonable to use for management
apps or for a single option (the file name) manually as needed. We'll
need to retain the old, more convenient syntax anyway for compatibility.
Your examples are mixed style already, so this is probably what you
intended anyway.
