New candidate JEP: 477: Implicitly Declared Classes and Instance Main Methods (Third Preview)

  Summary: Evolve the Java programming language so that beginners can
  write their first programs without needing to understand language
  features designed for large programs. Far from using a separate
  dialect of the language, beginners can write streamlined declarations
  for single-class programs and then seamlessly expand their programs to
  use more advanced features as their skills grow. Experienced developers
  can likewise enjoy writing small programs succinctly, without the need
  for constructs intended for programming in the large. This is a preview
  language feature.
