In Kotlin a "receiver" is the instance on which an extension function is defined, or the type for a lambda with receiver.

If you want to iterate over all the entries of a known enum class, you can use the ‘.values()’ function. If you are working with generic enums, you can use the ‘enumValues()’ function instead.

JetPack Compose has a very strange
way of describing columns and rows.

The calls to StartScreen, MiddleScreen, and EndScreen might happen in any order.

This means you can't, for example, have StartScreen() set some global variable (a side-effect) and have MiddleScreen() take advantage of that change.

Instead, each of those functions needs to be self-contained.

We are finally getting the ability to animate Lazy list's item position changes in #JetpackCompose just like we did with DiffUtil 🎉

The Modifier API called `Modifier.animateItemPlacement()` was implemented and merged and will probably be released in an upcoming Compose version.
