Issue #21674 has been updated by Earlopain (Earlopain _). Bisected to https://github.com/ruby/prism/pull/3560/commits/915f6b3ae90aae73bb438e51fb9b... ---------------------------------------- Bug #21674: Possible regression in return case in statement https://bugs.ruby-lang.org/issues/21674#change-115159 * Author: jandudulski (Jan Dudulski) * Status: Open * Assignee: prism * ruby -v: 3.4.6 * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Suddenly my code started failing in Ruby 3.4.6 and 3.4.7. Shortest code example: ``` ruby args = [:increased] context = Data.define(:event).new(:decreased) case args in [event] context.event in ^event end ``` In Ruby prior to 3.4.6 it returns `false` (as expected) but in 3.4.6 and 3.4.7 it returns `:decreased`. `context.event in ^event` still returns `false`. -- https://bugs.ruby-lang.org/
