inline class can be declared as inline class and value class. why do both declarations exist? will one of them be dropped in stable release?

You define a value class with one constructor parameter and annotate it with @JvmInline. We expect everyone to use this new syntax starting from Kotlin 1.5. The old syntax inline class will continue to work for some time. It will be deprecated with a warning in 1.5 that will include an option to migrate all your declarations automatically. It will later be deprecated with an error.

A bit confusing that the blog post is started with an introduction to inline classes using the about to be deprecated syntax... 😅
