The following JEP with scope "SE" has been proposed to target JDK 22:

  456: Unnamed Variables & Patterns

  Summary: Enhance the Java programming language with unnamed variables

  nested patterns are required but never used.  Both are denoted by the
  underscore character, _.

The announced deadline for feedback to jdk-dev is Thu 26 Oct 23:59 UTC:

to the Targeted state, indicating that the feature is expected to appear in
the specified release of the JDK Project.  For more information about states,
see the JEP Process document:
