That's a good argument if List, dependably, will not appear where
Directive COULD appear -- but that's hardly the case, is it? Not unless
you personally wrote the code, wrote it SINCE Directive appeared on the
scene, and never slipped up and forgot to use it.
I suspect examples will eventually be found, though, where List can't take
the place of Directive.
