Issue #21048 has been updated by Earlopain (Earlopain _). Yes, I switched it up in the text. Fixed ---------------------------------------- Bug #21048: [Prism] rescue in modifier form with condition behaves differently https://bugs.ruby-lang.org/issues/21048#change-111573 * Author: Earlopain (Earlopain _) * Status: Open * ruby -v: ruby 3.4.1 (2024-12-25 revision 48d4efcb85) +PRISM [x86_64-linux] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- With the following code there is a discrepancy in how prism and parse.y consider precedence: ```rb $called = false def foo $called = true end foo rescue nil if false puts "Called: #{$called}" ``` Prism interprets it as `(foo rescue nil) if false`, not calling the method. `parse.y` does `foo rescue (nil if false)` since at least Ruby 2.0 ```sh $ ruby -v ruby 3.5.0dev (2025-01-19T12:44:20Z master f27ed98eff) +PRISM [x86_64-linux] $ ruby code.rb Called: true $ ruby --parser=parse.y code.rb Called: false ``` -- https://bugs.ruby-lang.org/
