instance method do not work on functional component... i.e Can't use vue-i18n inside

What problem does this feature solve?

currently I can’t use vue-i18n in functional components…

<div class="banner_dl columns">
          <a
            class="banner_dl_btn column is-narrow"
            href=""
            target="_blank"
            rel="noopener noreferrer">
            <img src="http://placehold.it/218x64" :alt="$t('buttons.download_android')">
          </a>
          <a
            class="banner_dl_btn column is-narrow"
            href=""
            target="_blank"
            rel="noopener noreferrer">
            <img src="http://placehold.it/218x64" :alt="$t('buttons.download_ios')">
          </a>
</div>

What does the proposed API look like?

there’s no API for that, it just have to work out-of-the-box

Use parent.$t

The fact about parent, yes. But, it would be more helpful on vue-i18n docs. I don’t know if it’s there, but if it isn’t you should open a PR in their docs
