New candidate JEP: 463: Implicit Classes and Instance Main Methods (Second Preview)

[Mark Reinhold]

https://openjdk.org/jeps/463

  Summary: Evolve the Java programming language so that students can
  write their first programs without needing to understand language
  features designed for large programs. Far from using a separate dialect
  of the language, students can write streamlined declarations for
  single-class programs and then seamlessly expand their programs to use
  more advanced features as their skills grow. This is a preview language
  feature.
