I would say: feature should be dual-life. If I say

    use feature ":5.12";

feature.pm will attempt to emulate the features of 5.12 as far as
possible on the perl it's running on. In a case like this, where we are
talking about adding a keyword we already have an XS implementation for,
that's easy.
