JEP 456, Unnamed Variables and Patterns, has been promoted from Candidate to Proposed to Target for JDK 22. This JEP proposes to finalize this feature after one previous round of preview: JEP 443, Unnamed Patterns and Variables (Preview), delivered in JDK 21. This feature will 'enhance the language with unnamed patterns, which match a record component without stating the component's name or type, and unnamed variables, which can be initialized but not used.' Both of these are denoted by the underscore character as in r instanceof _(int x, int y) and r instanceof _. The review is expected to conclude on October 26, 2023.
