| Subject: | determine if a retry within callback |
when debugging, i want to use the callback to print out a message if a retry has happened. that doesn't seem possible to do currently. the only way is to check the value of $pause_if_unsuccessful, but that would only work if the values are unique. maybe if @timing_tries was consumed while iterated so when it is passed in to $after_c, the user could easily see how many retries were performed.
