Issue #7704 has been updated by drbrain (Eric Hodel). Target version set to next minor ---------------------------------------- Feature #7704: Add a list of enabled (experimental) language features. https://bugs.ruby-lang.org/issues/7704#change-35640 Author: mpapis (Michal Papis) Status: Open Priority: Normal Assignee: Category: Target version: next minor With multiple Ruby implementations and "experimental" features like "refinements" it would be nice to have an array or hash including list of enabled language features so developers could check it instead of auto-discovering code with some hacks. Additionally a new keyword like `require_features :refinements, ...` could be introduced to allow easy validation via either exception or return status. -- http://bugs.ruby-lang.org/
