Hello, We are planning to finalize the two pattern matching JEPs in JDK 21. Drafts of these final JEPs are available here:
Pattern matching for switch: https://openjdk.org/jeps/8300542 Record patterns: https://openjdk.org/jeps/8300541 We're proposing some small changes from the preview versions about to appear in JDK 20. These include: - We're dropping parenthesized patterns. They were leftover from a previous version of patterns, and they weren't used very much. They complicate the spec for not a lot of gain. - We're going to support case labels that are the qualified name of enum constants, and allow switches over non-enum types to have enum case labels provided they use the qualified names of the enum constants and these labels are assignment compatible with the switch type. - We're dropping the support for record patterns in the header of enhanced for statements. These will re-appear in a separate forthcoming JEP. Please take a look at these new JEPs and give us your feedback (either on this list or directly to me). Thanks, Gavin
