Issue #21608 has been updated by Earlopain (Earlopain _). To elaborate, if you replace `break` with a method call, it was already a syntax error. I suspect this was changed with https://bugs.ruby-lang.org/issues/21540. Such code has been rejected since at least ruby 2.0 and was only accidentally accepted since 3.4.0 ---------------------------------------- Bug #21608: 三項演算子と break を組み合わせると SyntaxError https://bugs.ruby-lang.org/issues/21608#change-114649 * Author: ursm (Keita Urashima) * Status: Rejected * Assignee: prism * ruby -v: ruby 3.4.6 (2025-09-16 revision dbd83256b1) +PRISM [x86_64-linux] * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: REQUIRED ---------------------------------------- ```
