     * *reported globally rather than propagated*: nothing at the call site could
     * catch it, and the element's connect was abandoned partway through.

     * Since 4.7 `use()` does not throw. Libraries register themselves, so `use()`
     * takes a name whether or not its pack has been imported yet, and `get()`
     * does the complaining, since it can say what *is* registered. The set of
     * valid names is open, and `oneOf` would silently rewrite a consumer's own
     * registered library to `phosphor`: the same blank-icons-and-silence failure
     * #79 was about, aimed at the other end.
