 <!-- Dedicated `Reflect` implementation for `Set`-like things -->

-<!-- TODO -->
+Inside of `bevy_reflect`, every reflected Rust object ends up being mapped to one of a handful of [`ReflectKind`] variants.
+
+Before Bevy 0.15, sets (like [`HashSet`]) were treated as opaque "values": there was no way to view or modify their contents via reflection.
+With these changes, we can now properly represent sets of all kinds, which is particularly handy for runtime debugging tools like [`bevy-inspector-egui`]!
