JEP proposed to target JDK 23: 477: Implicitly Declared Classes and Instance Main Methods (Third Preview)

[Mark Reinhold]

The following JEP is proposed to target JDK 23:

  477: Implicitly Declared Classes and Instance Main Methods (Third Preview)
       https://openjdk.org/jeps/477

  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.

Feedback on this proposal from JDK Project Committers and Reviewers [1]
is more than welcome, as are reasoned objections.  If no such objections
are raised by 23:59 UTC on Tuesday, 21 May, or if they’re raised and
then satisfactorily answered, then per the JEP 2.0 process proposal [2]
I’ll target this JEP to JDK 23.
