After playing and testing compose strong skipping mode, I've decided to make all Kilua HTML composable functions skippable by dropping return values (Composable functions that return values are never skipped). This allows to use this mode for better performance. But since accessing components references is an important part of Kilua API, I've introduced a twin functions (with Ref suffixes) for almost every composables declared in Kilua.
