Issue #21041 has been updated by alanwu (Alan Wu). Without any concrete design proposal and implementation, I'm afraid this boils down to "enums in ruby would be nice". I think successful feature proposals need more details than this. ... Am I talking to an LLM? ---------------------------------------- Feature #21041: Enum class https://bugs.ruby-lang.org/issues/21041#change-111540 * Author: dsisnero (Dominic Sisneros) * Status: Open ---------------------------------------- Enumerations (Enums) represent a critical abstraction in modern software design, offering significant advantages in type safety, code readability, and system-wide consistency. Most contemporary programming ecosystems—including Java, C#, Python, and Kotlin—provide native enum support, recognizing their fundamental value in representing finite, well-defined sets of values. Beyond basic type definition, enums are increasingly central to interoperability across serialization frameworks. Industry-standard specifications like OpenAPI, Protocol Buffers, and gRPC leverage enums as a canonical way to define constrained value sets, enabling robust code generation and cross-platform compatibility. Implementing a comprehensive Enum class would: - Standardize constant representation - Facilitate seamless code portability - Enable automatic code generation for documentation and client libraries - Enhance type safety and compile-time validation - Improve developer productivity through clear, self-documenting code structures By adopting a robust enum implementation, we can align our development practices with contemporary software engineering principles, reducing complexity and increasing overall system reliability. -- https://bugs.ruby-lang.org/

Issue #21041 has been updated by ufuk (Ufuk Kayserilioglu). I think the main feedback is that a feature request needs to fulfill the criteria listed here: https://github.com/ruby/ruby/wiki/How-To-Request-Features As @alanwu said, without a concrete design proposal, there is nothing to really discuss, since the devil is in the details. ---------------------------------------- Feature #21041: Enum class https://bugs.ruby-lang.org/issues/21041#change-111542 * Author: dsisnero (Dominic Sisneros) * Status: Open ---------------------------------------- Enumerations (Enums) represent a critical abstraction in modern software design, offering significant advantages in type safety, code readability, and system-wide consistency.
