JEP proposed to target JDK 20: 433: Pattern Matching for switch (Fourth Preview)

[Mark Reinhold]

The following JEP is proposed to target JDK 20:

  433: Pattern Matching for switch (Fourth Preview)
       https://openjdk.org/jeps/433

  Summary: Enhance the Java programming language with pattern matching
  for switch expressions and statements.  Extending pattern matching to
  switch allows an expression to be tested against a number of patterns,
  each with a specific action, so that complex data-oriented queries can
  be expressed concisely and safely.  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 Wednesday, 23 November, 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 20.
