Issue #20444 has been updated by esad (Esad Hajdarevic). nobu (Nobuyoshi Nakada) wrote in #note-1:
`StopIteration.new(3)` does not set `result`, and no way to set it in Ruby level.
``` $ ruby -e 'e = StopIteration.new(3); p e.message, e.result' "3" nil ```
Thanks for the hint. It seems that subclassing StopIteration to provide result works: ``` class MyException < StopIteration def result = 5 end loop { raise MyException } # => 5 ``` ---------------------------------------- Bug #20444: Kernel#loop: returning the "result" value of StopIteration doesn't work when raised directly https://bugs.ruby-lang.org/issues/20444#change-108060 * Author: esad (Esad Hajdarevic) * Status: Closed * ruby -v: ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [arm64-darwin20] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- There was a https://bugs.ruby-lang.org/issues/11498 a while ago which was merged in, but I was surprised to find out that raising `StopIteration` in a loop like `loop { raise StopIteration.new(3) }` returns nil and not 3. -- https://bugs.ruby-lang.org/
