Issue #21540 has been reported by Earlopain (Earlopain _). ---------------------------------------- Bug #21540: prism allows `foo && return bar` when parse.y doesn't https://bugs.ruby-lang.org/issues/21540 * Author: Earlopain (Earlopain _) * Status: Open * ruby -v: ruby 3.5.0dev (2025-08-08T02:57:23Z master 3ad26d0501) [x86_64-linux] * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Code such as `foo && return bar` has been disallowed in ruby since at least Ruby 2.0. Prism allows it though: ``` $ ruby -cve "a && return foo" ruby 3.5.0dev (2025-08-08T02:57:23Z master 3ad26d0501) +PRISM [x86_64-linux] Syntax OK $ ruby --parser=parse.y -cve "a && return foo" ruby 3.5.0dev (2025-08-08T02:57:23Z master 3ad26d0501) [x86_64-linux] -e:1: syntax error, unexpected local variable or method, expecting end-of-input a && return foo ruby: compile error (SyntaxError) ``` The code seems to behave like I'd expect it to and I wouldn't mind it being accepted but it is inconsistent. -- https://bugs.ruby-lang.org/
