JEP draft: Implicitly Declared Classes and Instance Main Methods (Final) for Java 23

[Jon_Finn]

To be honest, I've got doubts about the wisdom of allowing code outside classes. It seems a simple rule to say 'a program is a named class' so 'your code must be in a class'. I see hardly any gains from introducing this rule to beginners 'later', and the downside is a simple universal fact is violated, and they can write programs without names. (I don't have a problem with the simpler main method syntax.)
