* Takes inspiration from `WP_Post` and adds sanity to comment caching. * Clarifies when the current global value for `$comment` is returned. The current implementation in `get_comment()` introduces side effects and an occasion stale global value for `$comment` when comment caches are cleaned. * Strongly-types `@param` docs * This class is marked `final` for now Props wonderboymusic, nacin.
