Feature #8693 » 0001-returning-from-lambda.patch

       * Raises TypeError instead of ArgumentError if the receiver doesn't have
         to_r method.
     * Proc
       * Returning from lambda proc now always exits from the Proc, not from the
         method where the lambda is created.  Returing from non-lambda proc exits
         from the method, same as the former behavior.
     === Stdlib updates (outstanding ones only)
     * Digest
